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

[dave73]

Anyone running 17x9 with 5" bs, on both front/rear with stock suspension location? If so what size tires and how is clearance?

[rtgreen]

can you run 15x8  4.5 backspace up front on a 70 cuda?    any problems?

That won't work on the front. Front tires are really close to the fenders with the 17x8's. Mine with rub every now and then when I'm turning while going through a dip in the road. The rears are really close as well. Some people have luck and they do fine. I had to trim the wheel lips about a 1/2 inch so they didn't rub hitting dips in the road at higher speeds. This 17x8 front and 17x9 rear.

Here's my stock 1970 A66 on 15x7 Torq Thrust wheels with 225/60/15s front and 255/60/15s rear.

So the 1970 challenger convertible I picked up recently has 245/60/15s on all four corners. When I back out of the driveway or cut the wheel too much the front tires catch on the inside of the wheel lip moldings. I tightened up the torsion bars a little and it helped somewhat but I think I just need smaller tires up front because it's still happening once in a while. I typically ran 235/60/15s up front on my other E-bodys. I'm trying to decide whether to go with the 235/60/15s or the 225/60/15s. Looks like the 235/60/15s are only .5" smaller in diameter and .3" narrower than the 245/60/15s I'm not sure that's going to solve my problem. The 225/60/15s are 1" smaller in diameter and .7" narrower then the 245/60/15s. Which way should I go?

This is 255/60 rear and 235/60 front on original 15x7's.  No rubbing issues on this car.

I put an A body rear under it, with 1 inch offset hangers now it all fits like I want it to

If the 235's fit on your other cars, then why wouldn't they fit on this car?

I don't know if you'd be up for changing out the rims too but, I run 245/60's up front on 15x8 rims.  4-1/2" backspace.  I believe the backspacing is the key factor. 
It's very close to rubbing on the inside but not the outside (Full disclosure - I had to go with stick on wheel weights on the inside and had to tuck in one brake line a bit as it was rubbing slightly at full lock, but these were easy fixes and I think the look is worth it)

17x8 with 245/45 and 17x9 with 275/40.  Car lowered 1 1/2 inch all the way around.

@Shane Kelley - I know this is an old post but curious how you lowered the front? I backed off the torsion bars to drop mine but then couldn't get an alignment right. looked awesome though (:
PS - I have 17x8 Cragar's front & back.

I used PST clocked torsion bars and Hotchkis adjustable upper control arms. The clocked torsion bars allow the car to sit lower but still maintain proper spring rate. Obviously the adjustable upper control arms allow me to get the alignment in spec.

As stated above, the rim's back-spacing is the key issue.  Next is the height (diameter) of the tire, as well as the width of the tire.

Those Year One 17x9 rims have the correct back-spacing to fit 275-40-17 tires on both Front and Rear of our E-bodies.  Those tires are actually pretty small in diameter...  and not really that wide... as some people think of the overall size.

[Brentstella]

Do you remember which back spacing you used on your wheels?

[70vert]

Yep, there is not much room in the front. I have 17x7 with 225/50 and the passenger side rubs at a full right turn crank. They have 6mm offset and 3.75" backspacing, which I believe is part of the problem but that is only size for Cragars. I think a 5" backspace would be too much.
PS: I have 17x8 with 255/50 on the rear, 4.5 backspacing and the tire is dead center in the wheel well.

Could you tell me where you found the wheels?

[BluRaySRT]

What brand of tire are you using?
