GPM Associated RC18T Rear Radial Tyre 40 Degree Insert AR893R40G Alternate Name  [AR893R40G]

RC18T rear radial tyre summary

This rear radial tyre is supplied as a matched pair for the Associated RC18T and carries the part number AR893R40G. The tyre uses a standard rubber compound and a 40 degree insert to influence carcass stiffness and rear contact patch behaviour.

Fit and compatibility: the listing designates this tyre for Associated RC18T rear wheels and hubs. Always confirm wheel hex and offset prior to fitting to ensure proper seating and clearance on your vehicle.

Installation notes: mount onto an RC18T rear wheel built for this tyre, orient the insert to match your wheel mounting practice, and use glue on the bead if you run glued tyres. Check that the tyre seats evenly and trim any flash to maintain balance.

Tuning role: the 40 degree insert gives more carcass support than softer inserts, which can sharpen rear-end response and change mid-corner balance. Use these tyres when fine-tuning rear traction versus oversteer on circuit or club nights.
