Mine are 12.5" wide, but they're 35's.I have been pricing out tires at a local place and I have found a good deals, but I am trying to decide how wide I want to go. 285x/75R16(~11.2" wide) or 305/70R16 (12" wide). I have 255/75R18 (10" wide) Bridgestone Dueler ATs now on factory 18" Polished 7 Spoke Anniversary Wheels.
Personally, I'd go with the 305's. You'll take a bigger hit on mileage due to weight and rolling resistance, and you'll lose a little more top end power. But neither of those would deter me.
Damn the 90-mile commute.
