Tires
1 report
“TIRES ARE 235/40 R18 REAR TIRES. This is the second set of these tires that have worn out after about 3500 city/highway road miles. No racing, no drifting, no tire spinning on launch. Porsche dealer replaced both sets as part of CPO process; now I need a third set. Current mileage on the car is 63590; I purchased it in Sept of 2021 with 57K miles. Tire wear is even across the tread; no alignment issues observed. Excessive wear was noted both times by the Discount Tire tech who checked the air in the tires at my request-routine for me. Last time, the tech said the tires were so bad he shouldn't put air in and I should get them replace ASAP. The danger arises from unexpectedly low mileage to complete tread loss and cord appearing without warning with the risk of a blowout at highway speeds on out of town trips. The excessive wear is being discussed in Boxster forums with no recognition that this must be a design or manufacturing defect unique to this model of tire. Please investigate.
