Associated RC 18T Rear Radial Tire AR889R30G 30 degree Insert for Tuning by GPM  [AR889R30G]

Rear Radial Tyre - 18T Fitment

This 1:18 rear radial tyre is supplied for Associated RC 18T on-road cars as part AR889R30G from GPM. It is produced in a standard rubber compound and fitted with an internal insert to maintain tyre shape during cornering and acceleration.

Fitment is intended for the Associated RC 18T platform; the radial section and 30 degree specification contribute to expected camber response when installed on standard 18T rear hubs. Use standard mounting routines for 1/18 on-road tyres, verifying bead seating and correct insert placement to avoid runout.

On track these tyres are a practical baseline for rear traction work, delivering consistent lateral grip and straightforward setup feedback for shocks and suspension. Remove debris from the tread and confirm insert seating after initial outings to ensure steady performance.
