TRX4M Adhesive Crawler Tyres 55x22mm TRX4MZSP24B by GPM  [TRX4MZSP24B]

Precision adhesive crawler tyres for TRX4M platforms

Engineered for TRX4M scale use, this tyre set combines a CNC-inspired approach to quality with a super-soft butyl rubber compound and internal foam inserts to enhance traction in technical crawling. The material is specified as super-soft (25 degree) butyl rubber rather than TPU/TPR, chosen for superior adhesion and resistance to tearing under sidewall load.

Design features include internal reinforcement and foam inserts sized to retain tyre profile and sidewall support under sustained load, improving stability and reducing progressive wear. The construction is optimised to reduce slippage on wet or smooth surfaces while maintaining a compliant contact patch for precise low-speed control.

Fitment and assembly notes for builders: these tyres are intended for 1.0 inch rims and use a controlled, slightly tight inner diameter to minimise rim slip. The bead uses an extended tongue profile and provision for longer fixing screws for direct mounting, and the narrow clamping thickness is specified to allow easier one-handed bead compression and consistent wheel assembly.
