GPM Associated RC 18T Rear Radial Tyres 40 Degree Insert AR900R40G Set  [AR900R40G]

Overview of 18T Rear Tyre

This aftermarket rear tyre pair is produced for use on the Associated RC 18T and comes as a single pair with internal inserts. The radial profile is matched to standard 18T rear wheel hubs and commonly used 1/18 touring-buggy inserts.

Performance and compound: the 40 degree rating indicates a firmer rubber that trades slightly less mechanical grip for improved wear and stability. On carpet or low-grip sealed surfaces these tyres deliver a predictable rear end that helps with lap-to-lap consistency.

Mounting advice: supplied inserts help maintain tyre shape. Make sure the tyre seats evenly on the rim before applying adhesive, trim any inner flashing so the insert lies flat, and routinely check balance and rotation to manage wear patterns.

Fitment details: intended for the Associated RC 18T platform and standard 18T rear wheels only. These items are RC parts and not for full-size applications.
