This GPM 1.9 inch rubber tyre uses an internal foam insert to stabilise the tread and maintain an even contact patch under load. The tyre outer diameter is 114 mm and the tread width is 44 mm, dimensions that suit many scale crawler applications. Use these tyres on compatible rigs such as the Axial SCX-10 II Jeep Cherokee, Vaterra Ascender Blazer K5, G-made Sawback 4LS, G-made Sawback, G-made Komodo, and Axial SCX-10 to refine traction and consistency on technical terrain.
