Associated RC18T Front Radial Tire 30 Degree Insert AR899F30G by GPM  [AR899F30G]

RC18T front radial tire

This purpose-built front tire is made for the Associated RC18T chassis and is supplied as a pair, identified by AR899F30G. The rubber radial profile with a 30 degree insert changes sidewall response and steering behaviour while keeping wheel geometry unchanged.

Mounting follows standard RC tyre practice: insert the 30 degree wedge inside the tire, seat the tyre on a compatible RC18T front rim, then secure with your normal mounting method. No special equipment is required beyond typical tyre tools and a wheel holder.

From a tuning perspective these tires influence front-end bite and initial turn-in. The radial profile combined with the 30 degree insert helps stabilise the contact patch under steering loads, letting drivers refine front grip balance without altering suspension pick-up or core wheel components.
