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

Rear radial tire for RC18T

This pair of rear radial tires is an RC-scale replacement intended for Associated RC 18T platforms and similar RC18T-compatible touring setups. The design centers on a standard rubber compound and a 40 degree insert to let drivers adjust rear traction and balance without changing other suspension or drivetrain parts.

Fitment and installation are straightforward: remove the wheel from the hub, separate the foam or stock insert if present, fit the included insert into the tire, mount the tire to the wheel, and reattach to the hub. Standard wheel hexes and glue mounting procedures apply; use appropriate wheel adhesive and let the bond cure before running.

Tuning role: these tires are intended for rear placement where radial construction and the specified insert angle influence slip characteristics and lateral stability. Expect adjustments to rear bite and rotation feel primarily through insert choice and tyre mounting tension rather than through electronics or suspension changes.
