So I buy this Roush Mustang with 18X9s in the front and 18X10s in the rear with 265/35/18s up front and 295/35/18s in the rear (the tires Roush puts on those wheels). The dealer promises me he will replace the tires, same dimensions, but instead orders 285/35/18s in the rear, obviously trying to save some money. I like the way the 295 fits on the rear right now and am worried that the 285 will damage this look. I have searched the forums and understand fully that bigger is better, and optimally I should get the 295, however, the dealer has ordered them and will not reorder the 295s. For those of you who have gone from a 285 to 295 or vice versus, on an 18X10 inch wheel, is the difference really noticable?
