Tires
06/11/2025
Started car in parking lot and warming light read zero air in right front tire. No prior warning. Checking tire for any road hazard - nails or other potential punctures but none were present but the tire had a hole just below the wheel that had blown out. The tire is a Pirelli P Zero 245/40R20 Run Flat. Was able to drive it to Tire Discount the next day to replace the tire. Manager checked tire and could not find any other issue with the tire. They were supposed to hold the tire but it was removed by the recycling company. I have pictures and the managers examination. Our safety any others if the split in the tire would have blown at speed in traffic. Called and emailed Pirelli and they could care less about a safety issue. Just told me it was out of warranty because it was over 1 year old. The tire has approximately 5,000 miles on it.
