The Dunlops "cupped". They looked like something on the rear of a John Derre.They wore so badly the front was replaced at 5K miles and the rear at 9K miles...they replaced the front with out much hassle, the rear took 3 calls and a letter to the factory from a lawyer.....calls to Dunlop were useless, to hear them tell it they didn't have a problem. Sent them pics still ,a dance on the outer end of the phone. There were several post here on the problem.
