Tamiya 24mm Tire Insert. Package includes two inserts. These are hard density rubber tire inserts designed to fit 24mm wheels. They come in pairs and the black color identifies the insert as a hard firmness.
NOTE: The firmer the insert the less traction your tire will yield. The softer the insert the more traction you will get out of your tires, but they will also wear out faster.
