I received a set of 4 Michelin Part no. 89946 245/40ZR18 MIC A/S 4 ZP Pilot Sport Tires in Oct, 2022. They were replacement for another set of defect Pirelli RFT Tires with rough ride problems.
After trying to drive them with bad balancing evident, I took them to a second dealer who tried 3 times to balance them, including a forced pressure balancing, and in their report, said to return them to the original dealer which I did.
After another forced pressure balancing by the original dealer, they were taken off and a warranty claim initiated with Michelin. Michelin failed in addressing the tires defects and issued no new tires or refund.
Both Pirelli and Michelin appear to have quality control issues on tires built during the 2020-22 pandemic. Quality control is not what it used to be.
I am contemplating at this point a small claims court action against all involved. I will never buy Michelin again.
