Stock Wheels and Wider Tires in Rear

[ShelbyMax69]

Hello all, does anyone have an idea of how "wide" of a tire I can put on a stock, 20" X 9.5" rear stock rim? I was contemplating on a 305 instead of the stock 285 but I have no clue on what the stock rims can actually take. Thank you.

I believe that 295/35 is the widest you'd want to consider installing on the factory rear 9.5" wheels to prevent rubbing. I've heard of some installing 305/35, but that's pushing it, and if you lower the car even a bit, you're going to encounter rubbing with the 305/35 and factory wheel.

Thank you for the information, greatly appreciated. It's good to know what options I have when sticking to the OEM wheels.
