Associated RC 18T Rear Rubber Radial Tire AR889R40G by GPM  [AR889R40G]

RC18T rear radial tyre replacement

This pair of rear radial tyres is a scale replacement made for Associated RC 18T platforms and similar touring builds. The tyres use a standard rubber compound and include a 40 degree insert so drivers can fine tune rear traction and balance without changing suspension or drivetrain components.

Installation is simple: remove the wheel from the hub, separate any foam or stock insert if present, press the supplied 40 degree insert into the tyre, glue the tyre to the wheel and refit to the hub. Use appropriate wheel adhesive and allow the bond to cure fully before running.

Tuning notes: these tyres are intended for rear use where radial construction and the 40 degree insert affect slip behaviour and lateral stability. Changes in rear bite and rotation are achieved mainly via insert choice and tyre mounting tension rather than electronics or major suspension setup.
