Has anyone tried a Rival 315/30/18 on OEM 18x10.5" wheels on the front of a C5ZO6? (ie for CAM-S)
Thanks in advance!

I run NT01's in the same size so it will fit if that's your concern!

Any rub and how far do they stick out?

Any pictures?

And has anyone tried a 335/30/18 Rival on the rear using the same OEM 18X10.5" wheels? I'm assuming that's too wide based on Tireracks specs for the 335 Rival. I'm basing that on the fact that the A7 does just barely rub into the inner wheel well and the specs indicate the Rival is about 0.7" wider then the A7 in a 335/30/18.

Check out mountainbiker2's post from the "315 Rival S or Falken 615" thread that's currently going.

Thanks, I didn't catch his reply stating OEM wheels. I was looking at photo with non OEM wheels on the front of that bfg challenge car.
So the only other question I have is even if I could use a spacer on the rear with an OEM 18x10.5" wheel and a 335/30/18 Rival would it make sense to squeeze that big of a street tire on that relatively narrow rim or just go to a square 315/30/18 Rival for obvious advantage in being able to rotate front to rear? Anybody tried that 335/30/18 Rival on the rear using OEM wheels?

I run 305 R888s in the back and have trouble keeping off the side walls...

Make sure you get the Rival S. I run that setup square. No problems at all.

No rub, here's a pic of the fronts under hard braking:

When I used to run 315/35/17s on 17x11 wheels Grand Sport offset ZR1 wheels on the rear of my C5 I noticed there was not a lot of space between the brake line and the wheel. As you try and cram more tire back there check the clearance to the brake line.

I think you'll be just fine using stock wheels, however they might just graze the inner fender liner depending on the condition of the liner hold down clips etc.

I'm running 18x11 et53 fronts with the 315/30/18 Rival S on my c5z which on the inside clearance is nearly identical to the stock 18x10.5 et58 wheels. however with the extra wheel width the center of my tire is actually .25" further towards the outside of the tire meaning I get no rub on the inside at all and a very very slight rub on the outside fender under hard/heavy bump/turns.
