Ive got a 1983 camaro with the stock rearend and i was given 315/35zr17s and im looking for a rim size that would work for my car. i was hoping to use 17x10 but with what backspacing. For the front i was going with a 17x8.

 

As far as I know, 315/35R17s won't fit on the front. Steering parts get in the way. I think you need to modify something up there, run HUGE spacers, or like an 18 inch wheel. Don't hold me to this, but I think something in that is right.

For the rear, I think you can run 17x11s with a 2 inch spacer (or a 4th gen rear, 4 inches longer overall,. end to end). Not sure on the offest and stuff. Go to skulte.com or PM askulte for info on that.

And the 315s require a 11 inch wide tire to fit. I'm pretty sure on that. 315 figures to about 12.4 inches of tread. And to put that on a 10 inch wide rim I don't see working.

You have a set of 4 tires? or 2?
This link should help. I hope. I'm planning on going with 315/35R17s rear, and 275/40R17s front.

 

17 x 11 wheels are needed. Spacer size will depend on which wheels you are using, the common offsets are 36 and 50mm. In the rear it is hard to get them completly tucked but it can be done.

 

you can squeeze a 315 on a 10-10.5inch rim..but it seems best suited for 11inch wides.

2 inch spacers for the rear and some inner wheel well work will be needed for clearancing but they still kinda will stick out to near the fender lip. 1.7 inch spacers are sold but you'll have to really beat the inner wheel well in to get it to tuck nicely and not rub.

but 315's are sick looking. well worth the work!!

do a search this has been covered tons of times

 

you are aware of the stress such a width will bring on that rear correct? be prepared for a rebuild soon..

 

That's what they make direct replacement 9" rears for!
