BMW X3 M tire size

Original tire sizes for the BMW X3 M, model years 2020, 2021, 2022, 2023 and 2024. Trim levels and wheel packages change the size within the same year, so confirm on the door-jamb sticker before ordering.

Front and rear Same size One size fits all four corners on the fitments we list.
Wheel sizes 21" Every fitment we list uses this diameter.
Tire sizes listed 1 One size per model year across the years we cover.

Check before you order. The surest answer is the tires on the car right now: the size is molded into the sidewall. The placard inside the driver's door tells you what the factory fitted. Our guide on reading a tire size shows exactly where to look.

What BMW approves

BMW

BMW-approved tires carry a star on the sidewall.

The star means BMW signed off on that exact tire for that car. Many BMWs also leave the factory on run-flats, marked RSC or with the maker's own code such as ZP or MOE, and BMW's own advice is not to mix run-flat and standard tires on the same car.

Brands that carry the approval

Michelin Pirelli Continental Bridgestone Goodyear

Written on the sidewall as: Pirelli P Zero (★), Continental PremiumContact 6 (★).

The drawing carries the sizes we list for this car, so you know what you are looking for. The placard on the car is still the final word, and it is the only place that gives the cold pressures: the number molded into the sidewall is the maximum the tire can hold, not what your car wants.

BMW X3 M tires: common questions

What size tires does a BMW X3 M take?

The most common original size is 275/35R21. Other model years and trims use different sizes, so check the list on this page and confirm against the sticker inside your driver's door.

You can, within limits: the overall diameter should stay within about 3 percent of the original, and the load index and speed rating must meet or exceed the door placard. Anything further changes your speedometer reading and can rub at full lock.
