If your back spacing is right..... 315/35-17. Without proper backspacing this could require fender lip rolling, BFH inner fender clearancing, or cutting the bump stops. If you aren't wanting to do any of that 275/40-17 is the stock 17" size. You can buy better performance tires in 275 for the price of or cheaper than junk performing 315's like Sumitomos. I find myself laughing when I see people running those when they could have had better peformance for less $ out of a better tire in 275.
