Tires Mounted Backwards
Just a quick Pro-Tip. Consumer Discount Tire Shops, like Americas Tires, Pep Boys, Walmart, Costco, etc. rely on volume sales and quick installs. So they might install your performance tires backwards on the rim. America's Tire doesn't do alignments, so when I took my BMW to the alignment shop, they noticed it and remounted the tire correctly for me.
Performance Tires and other tire models have the words INSIDE and OUTSIDE stamped on the tire. So when the Techs mount the tire on the rim, before spin balancing, there is a 50% chance of mounting the tire backwards. Back in the 1990s there were Unidirectional Tires on performance cars that had an ARROW stamped on them, so it is mounted correctly. I had Goodyear Unidirectional Tires on my 1994 Mustang Cobra. This applies to the Michelin Pilot Sport 4S tires that most of us run. The tread pattern is different on the inside vs the outside of the tires. This happened to me at America's Tire on my BMW F30 335i. First, the valve stem was defective/leaky, then another tire was mounted backwards. So mention it when getting tires installed at your favorite tire shop, and double check before driving away. If you are getting an oil change or other maintenance done on your M3, have them double check the tire fitment when your car is on the lift. Cheers |

When I bought my car in 2022 at a dealership, I had to tell them to swap one of the rear tires around for the same reason.
