Hi all,
I've confirmed that I do not like the 17" ralleye wheels on these classic muscle cars. This rules out the aluminum ralleyes. Nice wheels, just not for me.
So now I'm back to 15" steelies. I'm assuming that the US Wheel Steel Series 667 is as good as ever?
Been doing a lot of research. Here's what I ended up with for tire sizes for a "set it and forget it" setup:
Rear: 255/60/15
Front: 225/60/15 or 235/60/15.
The rear at 255 pretty much guarantees that you shouldn't have to massage the opening lip with the correct backspacing. That's not something that I would want to do. 255 should look decently "meaty" too without being overbearing.
The front...I'm not sure weather or not to go 225 or 235. Any pros/cons?
Looking for a nice staggered look, but nothing too aggressive. Getting new eaton springs in the rear is definitely on the list since the current HD 4-leaf springs are probably a big saggy and one side already has "helper" springs. Will come later. Getting rid of the 18 year old tires comes first though.
Question:
15 x 7 or 15 x 8?
Both these sizes with the "silver/chrome" look come in 4.5" backspacing only.
Hard to see but both these Challengers had 235X60X15 front and 245X60X15 rear on 7 inch wheels. The orange car was an A-66 but I powered it up a bit. For contrast the old photo of my FM3 Challenger shows 275X60X15 and 245X60X15 front, they were 7 inch wheels as well.
That Orange A66 has the perfect size tires/wheels IMO.
Sounds like 7" is the correct wheel to get, regardless of tire size for these beasts....
Do you know the backspacing of those wheels? 4.5" backspacing with steelies is my only choice. "assuming" that it's perfect...
I'm thinking 235 ft/255r is going to be the combo I may shoot for.....hell, even 245's may work for the rear, but those shadows in your photos definitely help "fatten" up the look a little....
The orange car's wheels were supposed to be 3 3/4 inch BS. I never did measure them to confirm though. With more BS you could run a wider tire. It seems to me the stock rims had 4 3/4 inch BS, I may be wrong on that though. I do know the aftermarket wheels moved the tire out enough to limit it to 245X60X15. I think with a 4.5 inch BS you could run an 8 inch wheel and most likely run 275X60X15 if you want to. Hopefully some other guys will respond to back that idea up.
Thanks.
Seems like my choice is going to be 15 x 7 w/ 4.5" BS all around. 255/60/15 in rear, 235/60/15 in the front.
You guys see any problem with this on a stock 70 challenger 340? I think it should look a tad bit aggressive, but doesn't stray too far from stock. I'd think proportions should be good.
Wondering thoughts on 225 vs 235 for the front. Pros/Cons?
That's a good recommendation. The 8" wheel in the rear will help fill space up more, I presume. And 255s should guarantee no rubbing.
What's the difference that a 15x7 vs a 15x8 wheel in the back make with the same backspacing?
Runcharger, what backspacing do you have on your wheels?
I'm still trying to determine if I want 15 x 7 or 15 x 8 in the back or not! Same backspacing at 4 1/2". Would the 8" wheel in the back give the illusion of a wider tire, even though the tire is the same size?
School me!
My Challenger was an A66 and I put 15s on. Rears one inch wider than fronts.
I get that, but I'm trying to visualize what it does.
15 x 7 w/ 255 rear tires vs 15 x 8 w/ 255 rear tirres.
If 15 x 7 and 15 x 8 provide same back spacing, then I assume the tire swill "push" towards quarter more with 15 x 8 rim.
Pros/cons?

Unfortunately mine is in the shop or I would run out and take some pictures for you ... get tire sizes ... etc. The dish on the back wheels is definitely deeper than the fronts. Here is the only pic I have on my computer.
Nice Pic! Looks good to me. I'm just wondering what the Pro/Cons of 15 x 7 vs 15 x 8 with the same 255 tire on the rear is.

I put wider tires on the back. That was why I got the wider rear wheels.
I ended up with 15x7 in front & 15x8 ralleys in the rear , I used the Nitto 555 275 / 50 / 15 on the rear with lots of room , I liked the look better with the wider 275 tread & the drag radial compound but with the shorter 50 series tire , the 275 60 looks too tall under there
Ugh, that's a different topic. I think 275 is too wide from what I've been seeing.....
I think I've nailed the tire sizes down as 235 and 255. You guys tell me if that won't look good....
All I'm wondering is for the rear rim, do I do 15 x 7 and 15 x 8. Either will work, I'm sure of it, I'm just wondering what the visual benefit is!
:pullinghair:
I do plan to get +1 rear leafs in the future....

I went through thinking about this. If you use the same width wheels front and back ... Then mount different size tires on the front and back ... There will be a different appearance. The bulge in the sidewalls will be different. Okay, I have been called excessively picky, but that made the difference to me. :haha: :wave:
Here s my set up: 15x8 4.5bs at the four corners
235/60 front and 255/60 rear
That should answer your question foe the look
QuoteI'm trying to visualize what it does.
15 x 7 w/ 255 rear tires vs 15 x 8 w/ 255 rear tirres.
The tire's sidewall will naturally bulge out past the rim lip. If you run a 15x7 on all four corners, the sidewall will bulge out more on the 255's because they are wider. By using an 8" wide wheel, you are pushing the bead out farther...reducing the bulge in the sidewall. The difference in the sidewall bulge might be noticeable if using 15x7's all the way around...it might not be. Some people might like that look...others may not. If you want to keep the sidewalls looking consistent, run the 8" wheel in the back. :alan2cents:
Another thing that hasn't been talked about is tire rotation. If being able to rotate your tires is a concern, then you'll want to run the 235-60's on all four corners.
Husk: That looks good but it looks like they may rub? How close are the sidewalls to the leaf springs?
Less back spacing will push the tire OUT towards the fender lip. More back spacing will bring it in closer to the leaf spring. It looks like 4.75" - 5" back spacing would work by the look of those pictures.(if those wheels really are 4.5" bs)
I'm surprised that with a 4.5bs and a 255 that it's that close to the fender. I always thought that 255s in the rear was a safe-bet fit.
Have you measured the backspacing of those wheels to verify 4.5 bs? Even the fronts look mighty peculiar.
If you compare with runcharger who has the same tires, he has plenty of clearance. You seem awefuly close...
QuoteHave you measured the backspacing of those wheels to very 4.5 bs?
:iagree:
Those are perfect on the springs. I really wish I could remember the BS measurement on my wheels on the orange car the American Racing spec doesn't seem right to me.

Well i was also surprised! Because i read everywhere on the boards that with 8" rims, 4,5" Bs was the best choice, and indeed the tire is close to the fender!
But i didn't verify ...maybe i received 4"! :rolleyes:
Really appreciate the responses you guys. Keep em coming if you have more combos/input that you'd like to share.
It seems the defacto choice if you're going with 255 on the rears is to choose an 8" rim. This will make sure the sidewall buldge is consistent. Not really any other reason.
The reason you'd want to go 7" all around is if you think at some point in the future you'll want to use 235's all the way around and this will allow you to rotate them, and take the risk that the "bulge" on the 255's on a 7" rim in the rear will not really be noticeable.
I think my next step is to wait till I get the damn car which is in 4 more days. Figure out what my current backspacing is on my 14" Ralleyes, and to do some mock ups and a lot of staring. :)
Yes that's the way to do it. You can seen how much space you have and go from there.
Not true , I had fitted 295s under there , did not rub but too close for comfort , 275 left plenty of room but with the correct backset of the rim which IIRC was 4.5"
I am running 15x7 up front with a 235 60R 15 tire and 15x8 (4.5 inch backspacing) in the rear with a 255 60R 15 tire, and to me this is the perfect setup. For a while I ran a 275 60R 15 tire on the back and it fit, however with a car full of 4 people if I hit a big enough bump the tire would rub the top of the wheel well (could have been remedied with a stiffer spring I suppose).
Now that I am thinking about it, this picture may have been while I was running the 275 tire.
There we go: That looks tough and it's all tucked in.
Alright guys. I've had plenty of time to stare and consider!
The 14" Ralleyes I haven't measured yet, but they appear to have lots of backspacing, which mean the wheel/tire looks REALLY tucked in. Like, almost too much tucked in. The 14" wheel is small, and the E70 tires (which come out to 215) look a little wimpy. Does anyone know the backspacing of the stock 14" Ralleyes...it has to be more than 4.5"!
At this point I'm pretty sure what I want to do. US Steel Wheel series 667 15" wheels 7" wide with 4.5" backspacing all around. 235/60/15 tires all around too. That should give the car a nice look/stance. Eventually will put on +1 leafs.
Radial TA RWL still the choice, or are there some other brands that have give a better tire with the RWL tire?
There's also the Mickey Thompson Sportman S/T
Picture is worth 1000 words
Had 2 fail last year driving to Carlisle
Wow, that sucks. Street radials are street radials (so I read) as far as traction is concerned (if that matters). Seems like the Mickey's are a runner up as the best street radials. I may grab a set...
Assuming that 235 tires on all four's with a 4.5" backspace will be golden.
Assuming that US Steel Wheels 667 series are the closest looking to stock. Chrome outside rim with silver on the inside. I like the the darker inner cap option to give it some break-up. 15 x 7s all around.
Shouldn't look "wimpy" and should look balanced.
Here is an A66 with standard 15x7's with 225/60's front and 255/60's back.
I determined that the factory 14" Rallyes are about 3 3/4" backspacing. Looks to be about 5.5" wide.
Going to a 15" US Sheel Wheel Rallye at 15 x 7" w/ 4.5" backspacing should look good. It will bring the wheel outwards about 3/4" along with the 235 tires to help eat up some of that empty space.
But I did notice a problem...my leaf springs have a helper springs on them! My springs are the correct A66 springs (4-leaf R/T springs). The helper spring mount would make contact with this new setup, so leaf springs have to come before tires/wheels, sadly.
Buying new 5-leaf springs with a +1 seams to be cheap and easy and is what most recommend. That vs removing helper springs, then getting my current springs re-arched. Pros and cons?
Is the US STeel Series 667 wheel the only one with a chrome around the rim?
https://www.uswheel.com/products/chrysler-rallye-silver
It seems like the Wheel Wheel Vintiques are either powder-coated in silver or everything is chrome.
If so I much prefer the US Steel wheel, because it exemplifies the "half moons" into full circles, which I think was the design intent of Chrysler.
Powder-coated silver keeps the half moons half-moons. Looks like a lowered tiered option IMO.
Chroming everything doesn't look stock and doesn't look right IMO.
Anyone with the US Wheel 667 series that can take a photos? It seems like these are the ones to go with, but I cannot find any real-world pictures!
I emailed US Wheel. Hopefully they can send me some real-world shots of this wheel.
I absolutely LOVE the look of this wheel, but I'm curious on how the "rim" is finished. It looks like chrome in image. Perhaps it's something else?
That's a generic trim ring by the look of it. The factory trim rings were not flat they were more rounded. And yes the cool thing about a 70 15X7 rallye wheel was that the factory trim ring reflected the openings and made them almost look like circles when viewed from the side. The 14 inch rallye wheels (along with the 71 15X7s) had brushed trim rings.
You mean the reflection of the rim, not the ring right?
Yeah. I have the original 14" rallyes. Complete with everything. But they need to go. The fender wells beg for more space to be eaten up!
Still waiting the email. I notice that US wheel offers 4.5 and 4.25 backspacing. I know that either will work with 235s all around. What will look better? No doubt "fuller" looks better. Thinking about grabbing the 4.25s all around now.
A really poor prototype, but I taped where the 4.5 bs rims would come out at. 4.25 bs rims would come out 1/4 further. For 235s all around, that might be a mean road look...
My thought is to remove the helper springs, mount the new rims/tires, and THEN reassess the butt height...
Help me spend money!
No one has given you an answer on the factory backspacing. I'll pull a factory 15X7 wheel out of storage tomorrow and get a measurement for you.
Okay: The factory back spacing on a 15X7 rallye wheel is 4.25". I have never used non factory rallye wheels or trim rings however I believe the aftermarket trim rings are narrower than the factory ones. So I believe they make the 4.5" back space wheels so the aftermarket trim rings will fit with no gap to the center of the wheel. This will mimic the factory look. If you use 4.25" back space 15X7 rallye wheels with aftermarket trim rings there will be a 1/4" space from the trim ring to the center of the wheel.
I may be wrong on that as I've never used aftermarket wheels or rings like I say however I think that is the deal.
This photo is of a factory 15X7 rallye wheel with a factory trim ring.
Hope this helps.
Hmm, thanks! Those are some nice 15 x 7 wheels! I wish I had those!
Here's the aftermarket trim ring. 15" diameter, 2" wide:
https://www.jegs.com/i/US-Wheel/947/TRSS3000-15/10002/-1
Sounds like it would still be safer for the best fit with the trim ring to go with 4.5" backspacing.
I'm a fan of the dark grey center caps:
https://www.jegs.com/i/US-Wheel/947/C56DG/10002/-1
The factory 15X7 trim rings are 3" deep. So the 3" deep trim ring will work with a 4.25" backspace wheel. 2 3/4" will work with a 4.5" backspace wheel.
I guess i'm a little lost on how the backspace effects the ring fitment. I could see how the size of the wheel (15 x 7 vs 15 x 8) affects the ring fitment, but I guess I just don't get how the backspace effects a trim ring. Maybe i need some illustrations.
At any case, I want 15 x 7 Rallye wheels that look original, that will make 235's look nice and chunky in the fender wells. I'm ready to order, but I don't feel like I'm getting closer to pulling the trigger.
The US Wheel Brand seems to offer the best looking (and most stock ) Rallye wheels. Wheel Vintages doesn't look correct.
I think I understand why the backspacing effects the ring. The rings draw "backward".
Upon further research, the 15 x 7's from US Wheel ONLY come in 4.5" backspacing. So that's a constant!
Looks like US Wheel sells multiple trim rings. They have 1.5", 2", 2.5", and 3".
The 3" Trim Ring that US Wheel sells stay "for 15 x 8 and 15 x 10 wheels ONLY".
Would that mean I need a 2.0" or 2.5" ring?
2.5" rounded: https://www.uswheel.com/collections/accessories/products/trim-ring-2-0-rounded
2.0" rounded: https://www.uswheel.com/collections/accessories/products/trim-ring-2-0-rounded
Sorry for the questions. I want to make sure I get this right!
OK, I am an idiot! :thinking:
For the longest time, I thought the "trim ring" was that little circular ring that went around the center hub piece. That's what most of the pictures looked like online so that's why I was led to believe that.
I'm now realizing that the trim ring is the actual the wheel ring...it's a large piece. In-fact, it's what gives these wheels the "bling"!
OK, now that we got that out of the way, this brings more clarity to the discussion. AWESOME pics Runcharger. Really appreciated.
I believe that US Wheel and Wheel Vintiques probably sell the same exact wheel. Both are "Made in the USA".
With that said, I think if I am sticking with 235 tires all around, I should consider 4.25" over 4.50". This will push out the wheel/tire a fraction more towards the fender and help "fill the space" up a little bit more. Plus, as you mentioned Runcharger, the stockies were 4.25".
BUT, if I'm hearing everyone correctly, if I get a 4.25" aftermarket Rallye wheel, I will have some gap between the inner face of the wheel, and the edge of the trim ring. This kinda sucks.
So now I'm back to figuring out which trim rings that will lead to a nice flush fit for 4.25" BS 15 x 7 Rallye wheel. Maybe since this thread is so convoluted I may start another thread that's aftermarket Rallye specific...
According to your measurements, I need a 3" depth ring. There is also the real possibility that I am fretting way too much over a 1/4" gap. That's not very big!
There you go: The big thing is you don't want those rings to be 1/4" too wide. If you order them together from the same place they should work or they'll take care of you. The Wheel Vintiques stuff seems to be okay and you can order them from Summit.
Here's an interesting question to you all...
I already have 14" Rallyes. Yes, they look cool. But aftermarket Rallyes are not necessarily "factory equivalents," either. I cannot get US Wheel, Wheel Vintiques to reply back to my emails. I'm pretty much asking them to take my money, but I would like to see real world pictures of the trim rings and the 4.50 and 4.25 BS wheels. It's not a hard ask.
I've been thinking of Magnum 500s in 15 x 7 w/ 4.25" bs. No trim rings to worry about "fitting" right or "falling" off. Plus, Magnum 500s look really good on Challengers, as do the Rallyes. 4.25" will allow 235 tires to look "just right" (my own mental guessing). 4.50" would work too (I'm guessing). I'm "guessing" that 4.25 and 4.50 would look close to the same, but the slight edge goes to 4.25s unless the driver has plans to put 275s on the rear (which I really don't). 4.25's also are a nice "median" backspace for the front and the rear.....
There "may" be a company that even makes cast aluminum in Magnums which would be a bonus!
Getting Aftermarket Rallye steelies is at least $200 per wheel. That's pretty close to aluminum pricing. Lighter wheels has many benefits, though I'm not really sure if cast aluminum is all that much lighter than cast steel. Opinions?
Can you guys give me a history of Magnum 500s? I've seen them in 70s Dodge ads. They're arguably just as originals as Rallyes, and it seems to me that aftermarket Rallyes are not even close to matching the originals. If only I had real 15 x 7 mopar Rallyes, I wouldn't be asking, but maybe it's good to stand back and look at Magnum 500s too...
Hope you're all enjoying this trainwreck of a thread. :)
The nice thing about Magnums is that you focus more on the car. The Rallyes kinda make you focus more on the wheels. My GF likes the magnums more. My dad is on the fence.
Dodge ad?
Both rallye and magnum are available in alluminum but in 17" . They are sold under Yearone but I think Summit also carry them now to avoid ridiculous shipping charges from Yearone.
Thanks. It's nice that they are aluminum, but 17's don't look right IMO.
Do you know if any other company makes 15 Magnums in aluminum?
Wheel Vintiques makes the Magnums as well. The stock Magnums on Mopars only came in 14 inch but yes you can easily get 15's all chrome. I think the only cast wheels start at 17 inch but I'm not certain on that.
My thought is that the 15 inch tire choice is drying up. If I was going aluminum wheels I would go to the 17 inch Magnums or Rallyes for the better tire choice.
Do you suppose my 14" rallye caps would fit on aftermarket 15" rallyes?
Yes they do.
Here’s alloy 15 x 7 magnums.
http://www.virginiaclassicmustang.com/mobile/15-x-7-Cast-Aluminum-Magnum-500-Wheel--P482330.aspx
Any reason those wouldn’t fit like a glove?
What’s the estimated weight savings per wheel with those compared to steelies?
Rule of thumb is 3-4lbs savings per wheel. So 12-16lbs total less.
The Drake Magnum 500 wheels are 16lbs each. They seem to be very good quality. You can get a set of 4 for $600.
They come with legendary branded "caps" so you can always switch to the "bullseye" in the future.
Here's the specs of the one I'm eye. Boy, it looks pretty darn close to the OEM 15 x 7 Mopar Rallye wheels.
Run-charger, do you mind throwing your 15 x 7 Rallye wheel on the bathroom scale, with the trim ring and cap?
20 lbs in unsprung weight savings I think is a pretty good upgrade. My thought is to buy these, and be on the lookout for original Rallyes. These wheels will help my performance goals too. :)
Ah: I put them back in storage now. I'm pretty sure the 15X7 is right at 30lbs for the wheel only.
30lbs? Holy crap. I mean wow!
Defiantly these magnums then! That would be 14lbs lighter per wheel! Totaling 56lbs lighter in unsprung weight. Or, basically my car losing 200lbs.
I think that makes this an obvious decision. Plus, I'll keep my original rallyes in the attic. :)
For future reference, I weighed a 14 x 5.5" Rallye w/ ring and cap mounted on an old Goodyear F70 polyglass tire.
44.6-45lb on the mark total.
I weight it with myself (subtracted my weight) and I weighed it by itself. Bathroom scale. Very similar results.
According to the internet, a Legendary Magnum 15 x 7 wheel is 16lbs. A Mickey Thompson Sportsman S/T 235/60/15 is 25.76lbs. This leads to a combined weight of 41.76lbs.
Pretty cool that I'll lose about 13lbs unsprung by going bigger and badder! :)
OK, enough talk from me about wheels and tires....whewww!
Cool stuff: I remember reading about the light wheels on the newer Shelby Mustangs. It was quite impressive the performance increase that lighter wheels make.
Sheldon, you're right on the 15 x 7 Rallyes. I had someone also confirm that they're about 30lbs right on the mark. With the same MT tires, that would be a total weight of 55.76lbs. Compare that to my upcoming 41.76lbs. 14lbs per wheel has got to "feel" different I would think!
Whether or not it matters to the person is one thing, but at least the facts are out there!
Wondering if you guys can help me. I'm likely going to be forced to order lug nuts.
I need 10 right-threaded, and 10 left-threaded ET conical lugs.
My wheel bolt length is 1" from the drum to the tip, and it's 1/2" size.
The Magnum 500 wheels are .875" (including bevel) thick around the bolt holes. That leaves not so much bolt protrusion.
It seems like I'm going to want something with some shank length. Seems to me that 1/2" shank length would be "optimal".
Must ET conical nuts i've been seeing have .3-.33" shank length, which would be the BARE minimum acceptable, and I think I can do better than just "skating" by. I don't want to be worrying about lug nuts.
I'm assuming I should be 13/16" Hex Head, 3/4" hex, and 1/2-20 thread size.
Is there a lug nut place online that can get me what I need? Or perhaps made-to-order?
I didn't know that lug nuts are one of the biggest pain in the butts.

RE the bolded above, I'd really question that a 15x7 Magnum is only 16#. That is less weight than my Aero race weight wheels that are not D.O.T. approved. If a 15x7 Rallye is 30#, I don't see where there is so much less metal for a Magnum to be half the weight. I'd guess it to be a few pounds lighter, but that's about it.
Measured my Alloy 500 wheel & 235/60 tire, fully inflated including center cap (which weighs practically nothing), and wheel weights from balancing. 42.6lbs. So yep, the Magnum 500 alloy is indeed 16lbs raw.
You may be thinking of an OEM steel version?
Now if I can figure out who the hell can make my lug nuts to mount them.....
The old steelies are certainly cool, but my point is you should be mindful of how much rotational weight you are adding to the car by adding 15" steel wheels...
Then again, if my car was born with 15" Rallyes, I would have left them on. 14" Rallyes look puny and just had to go...in my attic in safe keeping! :)
Missed the alloy part of the conversation. My mistake.
Wild RT is hooking me up. Hopefully he can post some cool pics of his lathe job soon. Stay tuned....
An old topic but did you end up getting 235/60/15s fronts and 255/60/15s rear on 15x7s? If so would be great to see some photos please?
I still currently have 235's all the way around on 15x7s. It really looks good!
After the stroker kit, I'm probably going to want some more tire eventually. 255's is a bit borderline on 15x7s though. I may be compelled to get a wider rim...still debating. I think it will "work", but it won't be optimal.
I do have some pictures of 255s on a challenger on the rear (and 235s) and I think it looks really good. It's on my friend's car. I'll ask him if he can send me some pictures.
I find that 275s always overtake the styling given the mid-section bodyline. Cudas seem to be able to visually get by with 275s.
Thanks for your reply. I have 15x7s all around on my A66 and have just bought 255/60/15s for the rear, so will take a photo of what it looks like when done. There are 225/60/15s on the front so hoping for some stance to the car. They're going to be a job to fit as new rear quarters were fitted to the car and there are huge lips on the wheel arches, with spot welds, so am going to have to be careful grinding them back. I have a 1/3 of an inch I can cut back.
I'm guessing 255/60/15s on a 15x7 will have an arch in the centre of the tire, rather than be flat like on a 15x8?
Thanks again for the information.
With the correct backspacing, 255s should fit easily in the challenger's wheel well with room to spare--that is on the stock rear-well.
Please take a photo when it's mounted. I was surprised at how good 255s looked on my friend's car. It was meaty, but also "well kept and contained". From all angles it looked basically "stock" until you got in the very rear then you could tell they are wider than stock. I think you will be very happy. 235-255 IMO "looks right" on a challenger on the rear that still give it a sleeper/stock look.
255's on a 15x7 will have more sidewall bulge for sure. the tire will look more "flat" on a 15x8. It would be nice for others to chime in, but from the research I've done, it is "borderline" at best to put 255x60x15 on a 15x7. It means you'll have more sidewall flex. If you're rallying the car, it won't be very ideal. But if you're just going for cruises, and hitting the drag strip, it will probably be "fine", al though I'd worry about if it would wear consistently.
If money isn't an option, and if you are not already running the original wheels, you can easily just order 2x 15x8 wheels and then feel much better about mounting 255s. That's probably what I will do when I eventually upgrade.
Don't forget to replace your speedo gear.
btw, nice Les Pauls. I still have mine stored in cases.
Yes, that's the look I'm after, tire bulge, a bit like El Hemi's 70 Challenger. He has Polyglass G60-15s on the rear of his 70 Challenger, which are similar in size to the 255/60/15s. Yes will post some photos.
Here's El Hemi's car:
Yep...that's about what 255s will look like. Perfect size as the tire doesn't poke out at you.
:alan2cents:
E60-15 ~ 225/60/15
F60-15 ~ 235/60/15
G60-15 ~ 245/60/15
H60-15 ~ 255/60/15
J60-15 ~ 265/60/15
L60-15 ~ 275/60/15

That's a good point. I have 255/60/15s on my Mach 1 Mustang and there are definite scraps in the side walls where the tire has come in contact with the wheel arch rim. I'll have to keep these tires pumped up to 35psi and take it easy around corners.
Re the guitars, thanks for your comments, I have about 20 guitars at the moment, probably owned over 100 in all. My best guitar is the Gibson Les Paul 2005 Standard Faded. Nothing has ever come close.
I fitted the 255/60/15s to my 340 yesterday. I cut inner lip on the arches back, sealed the inside and then fitted them, they seem to fit nicely. They give car a little more stance.
Look awesome.
I personally would like the rear just a tad lower, but that's preference. I'm assuming you have +1" springs as well?
Thanks. I didn't add the leaf spring in the end. The tire is on a 15x7 so it seems to be sitting taller. I also have lower profile 225's on the front which makes the back seem higher.
Also I've noticed for some strange reason 255/60/15s appear taller than 275/60/15s on 15x8s. They shouldn't do but the cars I've seen with 275s seems to sit low and wide.
El Hemi's Challenger has a very similar size to the 255's and that looks perfect to me.
Here's a clearer shot of the tyres.
Here are some shots I took of a Cuda and Challenger with 275/60/15s on the rear. They seem to sit low.
Those other shots look awesome! Sounds like you got it pretty darn dailed in!
Once your fronts wear out, you may consider going to 235s.
I kind of like the look of it as it is. And I'm a kid of the 70s and like that 1970s street machine look. This looks right to me!
Kid of the 90s myself. :bradsthumb:
Love mine. Better than stock, but still flat and mean.
235s all around. I'm afraid to fuss with the stance because I find it perfect
Like I mentioned 255s look awesome on rear, but a raked challenger doesn't blend with the side lines for my eyes. Balanced with 235s in the front it may just look ideal even.
My pops is a fan of super raked stuff. I feel it. :)
Glad you like your new tires!
Another side shot. Was cold today.
This photo really screams challenger more than most IMO.
I also went with 235/60-15 and 15x7 all around.
Great shots! Thanks for sharing.
Took a shot of mine today.
this is 235/60r15 frt 255/60r15 rear. No engine.
That to me is perfect...that engine is going to settle that front down a little. Looks great already!
