The HUDY 836201F foam insert is built for 1/10 scale off-road rear tyres and comes as two pieces, giving racers a soft foam choice to improve tyre-to-track contact. It fits rear wheels for both 2WD and 4WD vehicles and aims to provide predictable rear traction and improved handling balance without modifying tyre tread or outer diameter.
Use this insert when tuning transient behaviour; the softer compound helps the tyre conform to bumps and can smooth corner exit transitions. Fitting is simple on most compatible wheels: push the insert into the tyre cavity, ensure it seats evenly around the bead, and confirm consistent compression once the wheel is mounted.
