    Since there are several application combinations possible, we've highlighted the easiest sizes to fit your Mazda. All listed sizes for each vehicle are wheel manufacturer-recommended fitments based on factory vehicle suspension components, and no vehicle modifications should be necessary.

    Should your vehicle have any modifications, then we can no longer guarantee fitment to your vehicle. If your Mazda is not listed, then this wheel does not have an appropriate size available for your vehicle or may be deemed as an aggressive fitment which will be indicated with the "❌".

    Installing aggressive wheels may require vehicle modification(s) and may be illegal for road use in some jurisdictions. Please check your local regulations before proceeding with your purchase.
