Can I fit a cheaper tire to a Mazda MX-30?

Mazda MX-30 tires

The Mazda MX-30 runs one fitment, 215/55 R18 95H. A standard load 95 rating is modest for an electric car and says something about where this one's curb weight sits.

Your own placard is the authority. You will find it on the on the driver's door jamb, on the B-pillar. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tire.

What changes on this car

Mazda fits the MX-30 with a single size in every market: 215/55 R18 95H, standard load at 690 kg per corner. Mazda's US manual lists it as an M+S all-season.

The battery is small for an electric car, at 35.5 kWh, which keeps weight down and lets it run a standard-load tire rather than XL. The R-EV version with a rotary range extender uses the same size.

In the US it was sold only in California and only for the 2022 and 2023 model years.
