2025 Mazda CX-50 Spare Tire
The Mazda CX-50, like many modern vehicles, does not come with a traditional full-sized spare tire as a standard feature. Instead, it incorporates a compact, space-saving temporary spare, commonly referred to as a "donut". This compact spare is designed to be used temporarily and only in emergency situations. The temporary spare tire for the Mazda CX-50 is typically smaller than the regular tires, measuring around 16 to 17 inches in diameter, depending on the model year and trim. It's important to note that this kind of spare should only be used to get the vehicle to the nearest service station or tire shop, and it shouldn't be driven at speeds higher than 50 mph. You should also factor in that driving on a donut for too long can potentially damage the differential due to the size discrepancy between the spare and the regular tires. Please consult your vehicle's owner manual for the exact type and size of the spare tire.
2025 Mazda CX-50 comes with 4 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 2025 Mazda CX-50 spare tire size.
