Big Wheels, 4"

4-Inch Big Wheels are inflatable tires for RC vehicles that deliver a smooth ride and easy setup, featuring positive-seal air valves and a tiny side valve for quick inflation or deflation.

Packaged as a pair, the wheels include two-piece bolt-together hubs and hub caps and are sized for axles with a 5/32-inch (4 mm) diameter, making them a practical upgrade for compatible chassis that benefit from reliable inflation and secure hub assembly.
