Thank you for viewing. This is a listing for Super Hard and Hard tires for Mini 4WD cars. These are standard size for low-profile wheels. Super Hard Black: for 7 cars Hard Limited Silver: for 2 cars Total: for 9 cars The Limited Silver tires come with carbon wheels, so they are hard to find. I am listing these to organize my spare parts. Perfect for replacing or repairing your machine, or for making hollow tires. No individual sales, please.
