This RC-scale kit contains two tractor truck units and a trailer section designed to fit selected TAMIYA models. The components permit wider rubber tyre fitment as listed in Compatibility and serve as a direct replacement or upgrade for scale tractor rigs.
Install the matched pair to change tyre accommodation or stance on compatible Tamiya tractor assemblies, using the existing mounting points where possible. Verify wheel clearance, track width and hub alignment before finishing assembly to ensure correct fit with wider tyres.
TTT-15445 is supplied as a tuning accessory to modify tyre accommodation and stance rather than steering or drive systems; check nearby suspension and body mount interactions during setup.
