These 1.0 inch crawler tyres are engineered as an aftermarket replacement for TRX4M-scale trail vehicles, incorporating foam inserts to increase lateral support and maintain consistent static height. The tyre compound is a soft butyl rubber around 25 degrees designed to improve contact patch adhesion versus harder materials, while reinforced construction improves resistance to tear and abrasion in technical trail environments.
Tuning and engineering notes: intended for narrow 1.0 inch bead rims, these tyres change traction characteristics, articulation response and steering feedback. The foam inserts limit excessive tread fold under load, providing a stable platform for tuning tyre profile and insert durometer on scale crawling builds.
Installation and fitment: mount on standard 1.0 inch bead rims used with TRX4M-class crawlers and verify rim inner diameter and hex adapter compatibility prior to fitting. Ensure foam inserts are seated concentrically and avoid over-stretching the bead during installation to preserve secure rim engagement.
