The TTT-15423 aluminium rear wheel and tyre set is a paired upgrade for TAMIYA Tractor Trucks sold as 2 pcs for the rear axle. It replaces the original rear wheel and tyre components on compatible Tamiya tractor truck kits and is intended for scale appearance and modest changes in wheel dynamics.
Design and role: each wheel features an aluminium centre mated to a tyre to provide a refined scale look and a different stiffness profile compared with plastic wheels. Use this set where you want a metal centre for aesthetics or incremental changes to handling.
Installation notes: the parts are designed to mount to the kit's existing rear hub interfaces and use the same fastening approach as the stock parts. Standard wheel removal and refit procedures apply; ensure proper tyre seating and secure fastener torque before operation.
Tuning and maintenance: aluminium centres can change rotational inertia and thermal properties; balance tyre assemblies for precise behaviour and inspect tyre seating after initial runs. Regular checks of fastener torque and tyre adhesion are recommended.
