The Mazda CX-90 replaced the CX-9 as the brand flagship three-row SUV starting with the 2024 model year. It is longer, wider, and more premium than its predecessor, and it debuted with an available plug-in hybrid powertrain. Tire selection should balance Mazda driving dynamics with the CX-90 family hauler mission — all-season performance, low rolling resistance for the PHEV, and ride quality befitting the flagship position.
Mazda CX-90 tire sizes
The 2024 CX-90 Turbo base uses 235/55R20 on 20-inch wheels. The Turbo S preferred and select trims use 235/50R21 on 21-inch wheels. Some premium configurations use 245/45R21 on 21-inch wheels. The PHEV shares the same wheel/tire packages as the Turbo variants.
Verify your exact size on the driver door sticker. The CX-90 is a new model and availability in larger 21-inch sizes is still building across tire brands.
