This is an RC-scale front tire set produced by GPM for the Associated RC18T platform, supplied with an internal insert and described in the item name as 40 Degree. The package is intended as a direct replacement or spare for the front end of RC18T 1/18 scale racing cars and is focused on tuning front grip and steering feel rather than being a universal tyre.
Installation is straightforward: the tyre mounts to standard Associated RC18T front wheels and uses the supplied insert to support tread shape and sidewall profile. Fitment requires correct seating on the rim and routine trimming or trimming of the bead if needed to ensure even contact; glue may be used if your wheel type requires tyre bonding.
Tuning role: these rubber radial tyres with insert let drivers adjust front-end behaviour by changing tyre compliance and contact patch characteristics. Use them when testing front grip, steering bite, or when swapping compounds during setup sessions on practice laps or local club races.
