These are scale RC crawler tires designed for TRAXXAS TRX4M platforms, supplied with foam inserts and sized nominally at 62mm outer diameter by 20.5mm width for 1.0 inch wheel applications. The compound is described as a low durometer butyl rubber formulated to increase traction on low-speed technical terrain, paired with a standard foam insert and internal reinforcement to help maintain shape under load.
Design notes from the source indicate a 25-degree soft rubber compound and an internal reinforcement that improves tear resistance. The tire construction aims to resist slipping in wet conditions compared with hard plastic-type tyres, and the foam insert offers additional sidewall support to stabilize the tyre under articulation.
Fitment and installation considerations: the inner diameter is intentionally slightly tight to reduce tire slippage on the rim, a long tongue at the bead area aids clamping, and the mounting method accommodates longer fixing screws for direct attachment. The clamping thickness is slim to simplify rim mounting and a one-handed compression tool is noted for convenience when seating the tire over the wheel and insert.
