The GPM TRX4MZSP22B tyre set is specified for use on Traxxas TRX4M and Axial SCX24 models where improved traction and resilience are needed. Produced in a super soft 25-degree rubber, the tyres provide approximately 35% more grip than common plastic alternatives. An internal reinforced layer improves tear resistance while the butyl rubber compound supports consistent performance in wet conditions. Foam inserts are supplied to increase internal support and maintain tyre shape on standard 1-inch wheels.
