Associated RC RC18T Rear Radial Tire 40° Insert by GPM AR893R40G  [AR893R40G]

Rear radial tire for RC18T

This is an RC-scale rear radial tire produced by GPM for the Associated RC18T platform, supplied as a single pair configuration as referenced by the part code AR893R40G. The tyre uses a standard rubber compound and includes a 40° insert intended to influence carcass stiffness and contact behaviour at the rear.

Fit and compatibility: the listing and part name identify this tyre for use on the Associated RC18T rear wheels and hubs. Confirm wheel hex size and wheel offset before fitting to ensure correct seating and clearances on your RC18T rear assembly.

Installation notes: mount the tyre onto a matching RC18T rear wheel, ensure the insert is oriented per your wheel mounting practice, and glue the bead if you use glued tyre setups. Check for even seating around the rim and trim excess material if necessary to avoid imbalance.

Tuning role: a 40° insert increases carcass support compared with softer inserts, which can sharpen rear response and influence mid-corner balance. Use these tyres when comparing traction levels or when dialing rear-end bite versus oversteer on track sessions.
