A wheel spacer is going to make it push out more, it won't stop any rubbing. You bought the incorrect sized tires.I am not the original owner. Have owned the P5 for 3 years. I just stood the new tire up against the old tire. Sits a lot higher. Old tire was low profile but same size tire. Would wheel spacer fix this problem? Cause I really love the new tires I got from Discount Tire.
