Associated RC 18T Rear Rubber Standard Radial Tires 40° with Insert by GPM AR900R40G  [AR900R40G]

Rear Standard Radial Tires for 18T

This is an RC-scale rear tire set produced by GPM for the Associated RC 18T platform, supplied as a single pair with internal inserts. The design is a standard radial profile intended to fit 18T rear wheel hubs and to work with common wheel inserts used on 1/18-scale touring buggies.

Role and tuning: the 40 degree mark in the product name identifies the compound hardness, which affects traction and wear balance on carpet and low-grip asphalt surfaces. Use these tires when you need a firmer rear contact patch that resists deformation under acceleration, and consider pairing them with suspension and differential tuning that compensates for reduced mechanical grip.

Installation notes: each tire comes with an insert to maintain profile and support. Check seating on the rim before final glue, ensure the bead sits evenly, and trim any flashing from the inner lip so the insert aligns without bunching. Balance and rotate tires as part of routine setup to track wear across runs.

Practical compatibility: intended for Associated RC 18T chassis and standard 18T rear wheels. These are RC-scale components only and are not for full-size or non-RC use.
