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

Rear radial tyre for the RC18T explained

Supplied as a single pair for the Associated RC18T, this rear radial tyre is listed under part number AR893R40G. It uses a standard rubber compound alongside a 40 degree insert to alter carcass stiffness and rear contact characteristics for setup work.

Fit and compatibility: this tyre is intended for Associated RC18T rear wheels and hubs. Confirm hex size and wheel offset prior to fitting to ensure correct rim seating and component clearance.

Installation notes: mount on a compatible RC18T rear wheel, orient the insert following your wheel mounting routine, and glue the bead if you are using glued tyre setups. Ensure the tyre seats evenly and trim any excess to prevent imbalance.

Tuning role: the 40 degree insert increases carcass support versus softer inserts, sharpening rear response and influencing mid-corner balance. These tyres suit riders testing rear traction and balancing oversteer against rear bite on track sessions.
