Note: The front wheels of the RS4 MT take HPI rear MT wheels! Remember this when you go to your hobby shop and they have a selection of HPI truck wheels available.
The front and rear axles of the RS4 MT take hex adapters. The hex adapters fit over the axles and spring pins, but the hex adapters can be removed so that Associated 10T, T2 or T3 wheels can fit on the axle. Losi XXT wheels will also fit on the MT axles if you remove the hex adapters.
