I know they should be the same no matter what brand you use but Michelins tend to be a little narrower than say Nittos. I have 2 cars with 275/40 -18's on the rear the Nittos are very tight w/ 18x8 4.75 bs and the Michelins are not. The car has been lowered 3" so it limits the front size 18x7 4.5 bs. w/235-40. I have no rubbing on the front a very slight rub in the rear under hard compression of the springs but not enough to damage the tire.

anymore pics that car is sweet love the color
