Engineered with emphasis on consistent behaviour and material durability, the GPM AR889R30G rear rubber radial tyres suit the Associated RC 18T where predictable traction is required. The 30 degree rubber compound balances wear and grip while the included foam inserts support tyre carcass shape, reducing deformation under heavy cornering and braking. These tyres are intended as a robust upgrade option for hobbyists seeking reliable rear traction across different surfaces.
