I have had 3 tire failures(blowouts)when I have hit potholes with my 21” wheels and Pirelli P Zero tires. I read on a MBZ Forum for my specific make of car - 2021/2022 MBZ S580 - that many others have experienced the same failures with these Pirelli tires. Those that have Michelin have had none. With such a small area between the road and the rim afforded by super low profile 21” setups, a tire like Pirelli with a weak sidewall will fail when the car strikes a pothole or obstruction. Another owner on the Forum said when he contacted Mercedes, they said it was not their problem, but Pirelli’s. Meanwhile, there are thousands of owners with this combination, many of which have already experienced failures. Something needs to be done before there are injuries, or worse.
