Changed 16" wheels on my 2007 fit sport to 15" 195/55/15 heliums for winter. Changed this I recently to lightnings with directional 195/55/15 tires and difference from heliums to lighting wheels are about 1/4 backspace . Noticed rubbing or bottoming out in rear suspension. Haven't seen anywhere where there is any rubbing or cuts on tire. Plenty of room all around. Just wondering if maybe need shock extensions (shocks bottoming out) or if anybody else encountered this problem
