Made as a replacement tyre set for TRX4M-style trail rigs, these 1.0 inch tyres include foam inserts to firm the sidewall and retain consistent ride height. The tyres use a soft butyl compound around 25 degrees to enhance grip relative to harder tyre materials, and internal reinforcement aims to reduce tearing during demanding trail sessions.
Application and tuning: designed for narrow 1.0 inch rims, these tyres affect traction, articulation and steering response. The supplied foam inserts keep the tread profile stable under load, so changing tyre or insert choice becomes an effective tuning option for scale crawling where grip and controlled deformation are priorities.
Fitting notes: these tyres mount to standard 1.0 inch bead rims common on TRX4M-scale crawlers; verify rim inner diameter and hex fit before installing. Fit the foam inserts evenly and avoid over-expanding the bead to ensure a secure seat on the rim.
