I swapped on my Jeep's winter tires with higher backspacing wheels (4.5 to 5.5). The wheel track is much narrower as the wheels stick in farther. Put the tires on last night. Today, I was checking the tires on my parents' Focuscape and noticed this when I took a look at the Jeep. Real lucky here! Bet that would have made an interesting noise and smell about the time the sidewall let go ... Edit The leaf spring is touching the tire.
