I have Prodrive GC-010G wheels. I was wondering what is the widest tire that can be put on the back without having to roll the fenders. For now I am running Falken Azenis - Rt-615 and I will probably need to replace the rears in a few months. I am still on stock springs, but I also plan on lowering the car about 1 1/2" about the same time I change the tires. Here are the specs that I am running now:

Front 17x7.5 +50 225-45-17

Rear 17x8.5 +56 255-40-17

Thanks for your help

 

thats about the widest you can go without rolling your fenders

 

you can run a 265 on the 8.5, but It'll just feel like your car is floating though lol

 

With the 56mm offset I would not go past the 255.

 

just curious but what causes this? is it because the tire is pinched on the rim?
