Associated RC18T Front Radial Tyres - Rubber with 40 degree Insert AR898F40G by GPM  [AR898F40G]

Front radial tyre set for improved steering feel

These two front radial rubber tyres are made for the Associated RC18T and designed around a 40 degree foam insert. The rubber outer and internal foam work together to hold the contact patch stable so steering inputs remain predictable under corner loads. This product is for front installation on the stated chassis.

Installation is simple: insert the foam before mounting, seat the bead evenly, and apply glue to the rim where appropriate. Always confirm clearance against steering components and suspension travel; small trimming to the bead or insert can prevent interference with hubs or body mounts.

From a tuning perspective these radials influence initial steering bite and mid-corner behaviour. Changing insert stiffness or switching tyre positions side-to-side lets you tweak turn-in and transient characteristics without altering shocks or springs.
