Tamiya CR-01 Wheel Bead-lock CR01-04/SI by 3Racing  [CR01-04/SI]

Wheel bead-lock for CR-01

This bead-lock ring is made for Tamiya CR-01 wheel assemblies and carries the part code CR01-04/SI. It is intended to secure the tyre bead and keep seating uniform during running and setup adjustments.

The ring interfaces with the CR-01 wheel and serves as a clamp to fasten the tyre bead against the rim flange. Fitting replaces the outer ring of the wheel and uses the original screws, so you can rebuild the wheel without changing hub geometry.

From a tuning standpoint the component improves repeatability by limiting small tyre-to-rim movement during low-speed technical driving or trail work. Install it when consistent tyre placement is required for testing or when swapping compounds.
