Mazda Cosmo Aftermarket Wheels & Tires
Enhance the grand touring presence of your Mazda Cosmo with aftermarket wheels and tires designed for luxury rotary performance and Japanese collector styling. Whether you’re modifying a 20B-powered JC Cosmo (1990s) or restoring a factory twin-turbo coupe, we offer flush fitments in 17 inch, 18 inch, and 19 inch sizes. Most Cosmo JC models use a 5x114.3 bolt pattern and support staggered offsets for wide-body applications. Choose from JDM-approved brands like Konig, Vision, Niche, American Racing, and Ridler. Every wheel and tire package comes mounted, balanced, and ready to install. Call 320-247-6160 for help dialing in your Cosmo’s offset or fitment.
