As far as size goes, I currently have 15" Yoko stock tires. I'm looking to get continental DWS tires, but I want to up the size (as I don't have rims, only steel wheels) to increase my terrible ground clearance.
Would 17" tires be too big?
According to TireRack, 205/50ZR17 93W fits, as well as 205/55ZR16 91W.
