The GPM AW2206PH45 set is written for serious hobbyists seeking a performance oriented wheel upgrade. It combines precision aluminum beadlock rings with a reinforced nylon wheel frame to improve durability and maintain tyre profile under load. The 2.2" tyre and foam insert arrangement offers predictable traction and sidewall support, and the wheels fit using a 12mm hex for reliable mounting to common Axial and HPI hubs.
