Mazda CX-9 Spare Tire

The Mazda CX-9, a mid-size crossover SUV, typically comes equipped with a compact temporary spare tire or "donut". The size of the spare tire can vary depending on the model and year of the vehicle. Many standard CX-9s come with an 18-inch spare wheel, but some of the later models, like the 2021 CX-9, utilize a T165/90D18 spare tire. These compact, temporary spares are designed to save space and weight in the vehicle, and are only meant to be used short term and at reduced speeds, until the main, more robust tire can be repaired or replaced. Always consult your Mazda CX-9's owner's manual or contact a Mazda dealership directly to confirm the correct spare tire type and size for your specific vehicle model and manufacturing year.

Mazda CX-9 models manufactured from 2007 to 2023 have tires with overall diameter ranging from 29.6" to 30.1", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Mazda CX-9 years and trims.

Listed below are compact spare tire sizes that can fit some Mazda CX-9 vehicles based on acceptable tire diameter range of 28.7" to 31". Some CX-9 models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Mazda CX-9 spare tire size designated by vehicle's manufacturer.
