GPM Associated RC 18T Rear Radial Tyre AR889R30G 30 degree Insert Set  [AR889R30G]

18T Rear Radial Tyre Notes

This 1:18 scale rear radial tyre is intended for Associated RC 18T on-road setups and is issued under part AR889R30G by GPM. The tyre is moulded in a standard rubber compound and includes an internal insert that helps keep the profile consistent under lateral loads.

Designed for the Associated RC 18T platform, the radial profile and 30 degree specification affect how camber behaves on typical 18T rear hubs. Fitment follows common 1/18 on-road mounting steps with attention to bead seating and even insert placement to reduce imbalance.

As a baseline rear option, these tyres provide steady rear traction for drivers tuning roll and shock settings, giving reliable feedback during setup changes. Clear the tread of debris regularly and verify insert seating after the first few runs for repeatable results.
