This tyre set is intended as a direct replacement for TRX4M 1/18 scale models and is identified by part TRX4MZSP24A. Moulded in a super-soft 25 degree butyl compound, the tread is tuned to boost adhesion on rocky and damp terrain while foam inserts and internal reinforcement support the carcass.
The material is butyl rubber, not TPU or TPR, chosen for its tacky contact and predictable wear characteristics. Internal stiffening and a standard foam insert improve sidewall stability during technical climbs. The bore is purposely tight to reduce rotation on the rim and the bead features an extended tongue to ensure secure clamping.
Installation guidance: designed around 1.0 inch wheel diameters common to TRX4M platforms, these tyres accept a longer fixing screw and are compatible with narrow clamp rims. Wheels with a dedicated clamping tool allow easier one-handed seating of the tyre.
