E-Body Tire Sizes (what fits, what's too big, what looks good)

[303 Mopar]

Hankook Ventus V12 245/45/18 and 275/40/18 with US Mag U111 Rambler textured gunmetal grey 18x8 and 18x9.5.  The stock spring location gives abut 3/4" room, fits inside the rear quarters with no rolled lips.  Fronts also fit perfect, no rolled lips, not rubbing on frame.

Do you know what offsets?   @303 Mopar

i went with 255 on the front and 275 on rear.
Looks pretty sharp

I went with YearOne's 8x17 and 9x17 Mopar Rallye Wheels wrapped in Michelin Pilot Sport All Season 4 tires. 245/45ZR17 in the front and 275/40ZR17 rear. They fit perfect. No rubbing, no need to flair the wheel well, no need for a shackle relocation kit in the back. I am very happy with the look and they seem to ride great!!!

Nice 71. I have the same YO Rallye setup for about 8 years now. They are holding up well. But the aluminum is soft and the wheels are clear coated so a few scratches from driving. I am using off the shelf ceramic coating on them and it helps keep the shine and easy cleanup.

Thank you very much for the tip.  Much appreciated.

What many people overlook is that a 275-40-17 tire is actually a small diameter tire and not really that wide, either.   They fit very nicely on the YO 17x9 rims... and those rims have the correct backspacing... they will easily clear our E-bodies in both Front and Rear.

By the way, I recently purchased a set of ET LT-III 18x11, 5.5" backspace, running Yokohama AO52 ADVAN 20 TW tires, 295-30-18 ... Front and Rear...  stock location rear leafs. Car is set-up and used extensively for Autocross and road course events.... look me up on MOPARTY... many pics ... 2020 I used my old reliable Centerline X-series lightweight forged aluminum 16x10 rims (5" bs) with 255-50-16 BFG Comp-2 tires F/R... more commonly I'd use Hoosier A6 275-45-16 F/R.    For this year, 2021, look at MOPARTY pics and you'll see the car with the new 18x11 F/R rims (vintage mini-lite style). 

Ok.. before you ask, yes... I do have my lips flushed... done very nicely by a pro-body shop Mopar best-friend... they look stock and can I could still use the chrome trim lips if I wanted to (flushed as well).  Also, as I noted, the car is setup for autocross racing... suspension very stiff.... yet still streetable (highway preferred).

My car is recently pictured in some Mopar Action magazines.

Rather than read all ten pages to see if this has been covered, Does anyone know what is the largest tire (rear specifically, but all the way around as well) I can fit with a 2" drop? I want the fattest tires I can fit on the car with the 2" drop for a 1971 Convertible Challenger. Thanks Gents!

315/35x18 is possible all the way around. However, this will require a custom offset wheel that MUST be spot on to fit and the front alignment has to be set to compliment the articulation of the suspension to prevent interference.

If you aren't willing to drop $4k in wheels, then most guys are comfortable with 295 rear 275 front.

Thank you very much HP2. I do appreciate you taking the time to respond.

@MOPAR MITCH
Could you post or PM a link to the pics you mention?  I found the Moparty site but can't find any pics.  The ET LT-III has been on my short list for a long time.  I have a '66 B-body rear with 1" spring relocation I can go with, so if you are fitting a 295 with stock spring spacing, I should have a good shot with a 305 and potentially  315 in the rear if I can get the offset right and/or tweak it with spacers.  Although that 295-35-18 size has a pretty good selection to pick from.  Does that 5.5" backspace pretty much center the 11" wide wheel in the available space? 

[MOPAR MITCH]

The 5.5" back space on an 11" wide rim actually pushes the centerline out 1/2" towards the fender lips.   With a 10" wide rim, and 5.5" backspacing, that will center it.   Remember, you need to add ~1" (1/2" each side) to the overall rim width due to the thickness of the beads.  In other words, a 9" rim is 10" overall width; a 10" is actually 11" overall; an 11" rim is actually 12" overall width.   There is consideration of the front steering and tire section width that you have to keep in mind... I looked in detail at those matters... and decided to push it outwards just a little towards the fender lips.    Yes... my lips are flushed and slightly pulled outwards, but done so in a stock-appearing way that even the chrome lips would still fit (if I wanted to, but they are not on the car)... and my car is slightly lowered front and rear... AND... my suspension is very stiff for autocrossing/road course intentions (yet still not bad at all to drive on the street... favoring smooth roads/highways..

The pics on my car from MOPARTY are on their web-site and various coverage articles from the event... just have to search and click... then folders of pictures open up... lots of pictures!!!   Look for the light-blue Omni Turbo autocross car.. click on it... lots of multiple pics from the event and on my car.

try these couple links... and click on the blue Omni... and other pics.. they progressively open folders of pictures!

On both of these links, scroll down and hit SEE ALL PICS.

My rims are Team III ET vintage mini-lites... 18x11 with 5.5" backspacing... tires are Yokohama ADVAN AO52 size 295-30-18 front and rear (200 soft sticky tread wear... amongst the best for 200 Tread Wear autocross competition).   I'm running a stock E-body 8.75" rear end (unlike others that have switched to the ~68-70? narrower B-body rear end).

[70 Challenger Lover]

Recently tried out this combo, putting the 14" whitewalls and hubcaps in storage. 245/60 front and 255/60 rear. All on 15x7 magnum 500 style chrome wheels. I wanted to use a wheel and rwl tire that was different from the traditional Rallyes with bf Goodrich's

[704406]

Can somebody say for sure if 245/60/15 BF Goodrich tires will fit on the front of a 70 Cuda using the original 15" rally's she was born with?
I have 245/60/15 Riken tires on now but they are old, like 20 plus years old and they are only 25.5 inches tall.
Back in the 70's I took the E60/15's off and tried G60/15's but they rubbed the front lower corners of the fenders
E60/15's are 26.1 tall and the 245/60/15 bf's are 26.6 tall
I don't want to buy and try if I can avoid it.
Thanks Ken

[SFEBODY]

I had the 245's on ,y 70 Challenger and they fit fine no rubbing at all.

[704406]

Thanks for the reply, as there are limited amounts of tires in the 15" size and BF Goodrich are available in my area I guess all I can do is try them. 255/60/15 on the rear for sure
