Mazda CX-30 Spare Tire Sizes

The Mazda CX-30 has used a 5x114mm (5 x 4.5") bolt pattern for all models from 2020 to 2021 along with tire diameters ranging from 27.0" to 27.3" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Mazda CX-30 years and options. In this case, a 145/60R20 temporary spare tire is the recommendation for all applications.
