The new slim front wheels are designed for use with all popular carpet and AstroTurf(TM) surface tires. It features the same offset as our popular#9691and#96902WD front wheels, only with an optimized profile. The wheels are textured on the gluing surface for secure tire mounting and have a smooth polished face for a factory team look. They are lightweight, yet stiff to reduce wheel deflection under hard cornering.
