Wheels & Tires - 18x10.5 Z06 Motorsports -> widest tire choices?

I'd *like* to run a 315 on them as they will be on the rear, in particular GS-D3's. However, as we all know, those run pretty damn wide. If I decided to run 305's instead, are there many *good* quality tires that I'd be able to choose from? Maybe I actually can fit 315's but I'd like to make sure before I buy these particular size wheels. Furthermore, If I'm gonna be shelling out money for rims, I'd like to get some decent tires as well that are as wide as possible. I don't need to dead hook on the street as I still have the stock rear, but I'd certainly like to step up the traction as I'm looking to be at 500+rwhp by the end of the summer.

If you put Motorsports on your car we are definitely going to look like twins. Here is a pic of my new back wheel and tire combination :jest:

Haha, nice. Are those a different size wheel/tire combo?

I have 18x10.5's on the back of my car and I'm running a 295/35/18 toyo T1R its the biggest I could get in there without modifying anything the car is also lowered with a prokit

Well, I don't mind doing a bit of the BFH mod if it means I can get 305's or even 315's to fit.

315s would be pushing it. The contact patch wasn't designed for that kind of load.
