Mileage warranty is given (supposedly) by tire companies as a selling point to customers. It is implied that their tire will last for a certain mileage limit. Any time there is abnormal wear through non maintenance or abuse (burnouts, etc.) they will not warrant tire. True, most will replace or give credit for mfg. defects within mileage limits. I'm just trying to see what kind of response I get from Conti. We all know that the tires aren't going to last 60K. My point to them is why show a 60K warranty if the tires aren't going to last that long through usual wear and tear.
