TRX4M Scale Crawler Tyres 1.0-inch Foam-Ready - TRX4MZSP20A by GPM  [TRX4MZSP20A]

1.0-inch tacky crawler tyres matched to TRX4M

This 1.0-inch rubber tyre set is made as a scale replacement for TRX4M models. The compound emphasises adhesion and tear resistance, and the included foam inserts stabilise the sidewall so the tyre keeps its profile when loaded. The layout is optimised for scale crawling where traction and predictable deformation matter more than top speed.

Fitting is simple for 1/18 scale TRX4M wheels: the bead shape and clamping tongue reduce slip on narrow rims, and the longer fixing screw length is intended to make direct screwing straightforward on common wheel types. For setup, experiment with foam densities to tune sidewall compliance versus steering response - softer foam conforms better, firmer foam firms up steering.

Use this tyre set when you want improved grip on technical sections, damp rock faces or loose dirt at scale, and when you prefer a rubber compound that keeps consistent traction across multiple runs.
