For RC hobbyists tuning off-road setups, the Yokomo YAU-6734A U6734 foam tyre inserts provide a targeted rear-end solution. Built for 1/10 scale off-road vehicles, these inserts fit rear tyres on both 2WD and 4WD cars to enhance balance and traction across varied surfaces.
The medium-density foam supports the tyre carcass under load, helping to preserve shape during hard acceleration and cornering. This results in more consistent grip and predictable handling on dirt and loose tracks.
Fit the insert so it sits flat and centred inside the tyre before mounting on the wheel. Smooth out any folds and check the seating to avoid uneven wear and to keep the car tracking true.
