About 2022 Mazda Mazda3 fitment

The 2022 Mazda Mazda3 Preferred ships from the factory with 215/45R18 tires, giving a 25.62″ overall diameter and 787 revs per mile. This is the reference size the factory speedometer, odometer, ABS, and TPMS were calibrated against, so any replacement tire should stay close to 25.62″ to preserve correct readings. All 2022 Mazda3 trims share the same 215/45R18 factory size, so fitment is straightforward across the range. The smallest recommended upsize is 225/40R19 — a 1.83% diameter change — which keeps the speedometer inside factory tolerance while adding marginal ride height and sidewall compliance. The most aggressive option shown, 245/40R18, runs 0.38% taller and will likely need clearance checking on stock suspension. For a direct replacement, look for brands offering 215/45R18 in all-season, highway, or terrain-appropriate compounds — the OEM spec typically emphasizes fuel economy and tread life over grip, so aftermarket replacements often unlock better wet performance or off-road capability at similar cost. Before committing to an upsize, confirm wheel-well clearance at full steering lock and suspension compression, and verify the chosen size does not conflict with snow chains, tire-fit sensors, or any lift-kit hardware already installed.
