Tallest And Widest

my car has a set of 15x8 ralleys out of summit on the rear.with 265's on them.they also are a hair thickness from the springs. with people in the back they just barely touch.just enough to see a black spot on them. about like rubbing it with your shoe. have not had any issues and when tire is clean you cannot tell it ever touched.i have never measured the back spacing but it needs to be about .5 in less
