GPM Associated RC18T Rear Radial Tire 30 degree Insert AR899R30G Pack  [AR899R30G]

RC18T rear radial tyre overview

This single rear radial tyre is made for the Associated RC18T platform, part AR899R30G. The tyre uses a rubber radial casing with an internal insert and a 30 degree shoulder profile tailored for rear axle service on scale racers.

Fitment is specific to the RC18T rear and the item is sold as 1 pcs. The radial contour and insert keep tyre shape under cornering loads and produce a repeatable contact patch for tuning grip and balance.

Installation follows standard practice for rubber tyres with foam or plastic inserts - insert the core into the tyre, seat it evenly on the wheel, trim any excess and balance as required. Small changes to insert thickness or mounting offset will alter rear bite and rotation characteristics.
