For a 315, you should use 10.5" - 11.0" wheels and roll the inner fender lip. Getting wheels with the right offset is pretty important.

Streetlegal?

I have c5 DD 18x10.5 in the rear with 315s. You are going to most likely have to do the BFH mod so they don't rub. I plan on rolling my fenders too as an added precaution.

315-30/18 on 11s. Cut stops, BFH'd (slightly) and rolled fenders. Offsets are perfect but wasnt taking any chances

Are you looking to put 315s ALL AROUND, and not the 'staggered' setup soooo common/popular on here??

If so, go over to frrax.com, since everyone autocrossing in E/SP class, and those allowed by the rules to run 17" diameter wheels in road racing are ALL running that setup on their rides, on ALL corners.

My buddy had 315's on all 4 with 17 x 11 TT2's. Overly common wheel, but it worked really well. His car felt like it was on rails.

What are the BS OS recommendations for rear 315's on 10.5 or 11's?

My daily driver has NT-05 315's all around with ZR1 11x17 50mm replicas. I have 1/4" 6061-T6 hub centric spacers F&R. Rear also has BFH mod and tubular control arms. That works OK for V710's and A6's because the outer shoulder is rounded.

For street tires with square shoulders, it needs a bit more on the FR as on hard left lock it barely rubs against the sway bar arm. Rear also needs fenders rolled due to shoulders.

I'm swapping front hubs 1-2x per year, getting about 1.5-2 years per set of tires at < 1000 miles per month. Getting about 10-12MPG in the city but not trying for fuel economy. Tramlines badly on poor pavement and hard to get the tires hot compared to a narrower tire. But damn it's fun

Here's some 335s not tubbed on fender rolled. When I lower it ill probably have to tub and fender roll though




Here's 295s up front on 18s

For the rears had to remove the bump stop and beat the hell out of the inside fender well.

Fronts when it turns was rubbing on the bottom of the wheel well so my shop fabbed it up so the well turned in on the bottom so it doesn't hit. Can get pics if you want when it's out of the shop for exhaust install

'95 Formula with 315's on 17x11" ZR1 wheels. BFH a touch and trimmed bump stops. Please excuse the fact that it's dirty

I run 4 17 x 10.5 TTMs with 315s for autocross and track days.












The rear needed a little BFH mods and I wanted to keep the bump stops so I moved them in board a little. Plus I rolled the fenders. On the front I added a couple screws to the plastic inners fenders to hold them out better and off the tires.
