The GPM TRX4MZSP20A is designed for hobbyists who require a balance of grip and longevity on 1.0 inch wheel setups for TRAXXAS TRX4M platforms. The super soft 25-degree compound was selected to increase contact adhesion by about 35% relative to typical plastic tyres. An internal reinforcement layer improves tear resistance and extends tyre life, while the butyl rubber formulation maintains traction on wet surfaces. Supplied foam inserts stabilise the tyre profile under load, helping maintain consistent traction through technical sections.
