Saw in your original post you're running 265/35-19's, doesn't that throw the speedo off a bit, or you using reluctor wheels? I'm trying to go wide for my summer wheels/tires setup, thinking about going stock fronts 255/40-18 and going 295/35-18 in the rear, but worried about losing the bead running 11.5" wide tires on a 8" wide rim... At your power level, are you experiencing any loss of traction under hard acceleration? If not, then I have a long time before I have to worry about going wider in the rear, can save myself a couple hundred bucks on the next set of tires...
