Associated RC 18T Rear Radial Tyre AR889R40G with 40 Degree Insert by GPM  [AR889R40G]

RC18T rear radial tyre replacement

These rear radial tyres serve as direct replacements for Associated RC 18T vehicles and compatible touring chassis. They feature a standard rubber compound and a supplied 40 degree insert so drivers can adjust rear grip and rotation without altering suspension geometry.

Installation guide: remove the wheel from the hub, extract any foam or original insert, insert the supplied 40 degree insert into the tyre, glue the tyre to the wheel rim and refit. Use appropriate wheel adhesive and allow it to cure fully prior to running.

Tuning details: fitted at the rear, the radial construction and 40 degree insert influence slip onset and lateral stability. Expect to manage rear behaviour mainly through insert selection and tyre mounting technique rather than electronics or suspension overhaul.
