The 3 Brothers RC 4.75" Dual-Stage Anti-Foam Inserts (3brods4.75) are waterproof 3D-printed tire inserts designed for 1.9" rims and 4.75" diameter tires. The dual-stage compound lets you run a very soft tire that still handles superbly on side hills, gripping rocks better than ever — especially in wet conditions.

Tapered edges ease mounting and increase contact pressure. Made in the USA with US-sourced materials.
