Associated RC18T Front Radial Tyres AR889F30G technical brief by GPM  [AR889F30G]

Technical overview of front radial tyres

This pair of front radial tyres is intended as a replacement for the Associated RC18T front axle and is supplied with internal inserts as noted in the product title. The tyres are sized for 1/18 class front wheels and should be mounted to wheels with the correct bead seat and rim width.

Fitting procedure: place the internal insert into the tyre cavity prior to mounting, ensure the tyre bead seats uniformly on the rim, and verify there is no interference with steering or suspension components. The "30 degree" reference relates to a recommended mounting orientation used by the manufacturer in certain front-end configurations; confirm wheel geometry before final assembly.

From a setup perspective, these rubber radials offer a repeatable baseline for adjusting front-end balance during testing. Use methodical, incremental changes and record handling responses to evaluate steering behaviour and contact patch characteristics on the RC18T chassis.
