Hey guys/gals. I have a 15 BE. Tires need replacing already. I've read some of the threads and I want to upgrade and go non run flat, but Iv'e already had 2 nails and the run flats have saved my ass so I'm going to go back with those same tires. Question, can I go a 305 on the rear on the stock wheel? Also, how wide do you think I can go on the fronts? I don't track the car. It is my daily. Thanks!!
