Had the rear shocks replaced and the rear alligned. I'm still scrubbing rubber off the rear Michellins at an alarming rate. 1st set went in a 1000 miles "no hot rodding/racing" the fronts are perfect. I put another new set on the rear and had new shocks and an alignment done. I measured the tread to day and the new ones are 50% gone allready. Fronts show no wear. What is my next step?
