Associated RC18T Front Radial Tires with 40 degree Foam Insert AR898F40G by GPM  [AR898F40G]

Front radial tyre upgrade for steering consistency

This pair of front radial rubber tires is built for the Associated RC18T and accepts a 40 degree foam insert. The rubber tread combined with an internal foam core helps stabilise the contact patch and keeps a predictable steering feel under load. This item is intended as a front tyre accessory for the specified chassis.

Fitting is straightforward: push the foam insert into the tyre before mounting, make sure the bead seats evenly, and apply tyre glue to the rim where required. Verify clearance with steering links and full suspension travel; small trims to the bead or insert may be needed to prevent rubbing on the hub or body mounts.

On-track, these front radials affect initial bite and mid-corner response. Swapping inserts or flipping left-to-right can alter turn-in and transient behaviour without changing other suspension settings. Use these tyres when you want repeatable front feel on carpet or hard surfaces.
