2018 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.
2018 Mazda CX-9 comes with 2 OEM tire size options. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Mazda dealership to confirm the correct 2018 Mazda CX-9 spare tire size.
