Associated RC18T Rear Radial Tire 30° with Insert by GPM AR889R30G  [AR889R30G]

Rear radial tire for RC18T

This is a 1:18 scale rear radial tire designed for use on Associated RC 18T on-road setups, supplied by GPM under part AR889R30G. The tire uses a standard rubber compound and includes an internal insert to keep the tyre profile stable during cornering and acceleration.

Fitment is intended for the Associated RC 18T platform; the radial profile and a 30° specification indicate the intended camber angle behavior when mounted on typical 18T rear hubs. Installation follows standard tyre mounting procedures for 1/18 on-road cars, taking care to seat the bead and insert evenly to avoid imbalance.

On-track role: these tyres are a baseline option for rear traction tuning, suitable for drivers who want predictable lateral grip and consistent feedback for suspension or shock adjustments. Keep tyre surfaces clean and inspect the insert seating after the first few runs to ensure consistent performance.
