Associated RC 18T Rear Radial Tyre Upgrade AR889R40G by GPM  [AR889R40G]

Replacement rear radial tyre for RC18T

This pair of rear radial tyres is an RC-scale replacement suited to Associated RC 18T cars and similar tourer conversions. The tyres use a standard rubber compound and come with a 40 degree insert so racers can tune rear bite and balance without swapping suspension parts.

Fitment steps: remove wheel from hub, remove any existing foam or insert, insert the supplied 40 degree piece into the tyre, glue the tyre to the rim and refit. Follow standard wheel gluing practice and allow full cure time before running the vehicle.

Setup role: when mounted at the rear, the radial casing plus the 40 degree insert change slip characteristics and lateral stability. Fine adjustments to rear behaviour come from insert choice and how the tyre is mounted rather than from electronics or major suspension tuning.
