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

Bead-lock ring for CR-01 wheels

This is an RC-scale bead-lock ring intended for use on Tamiya CR-01 wheel assemblies, supplied under 3Racing part CR01-04/SI. The component focuses on retaining the tire bead and keeping tire seating consistent during routine running and setup adjustments.

The ring fits the CR-01 wheel interface and functions as a mechanical clamp that secures the tire bead to the wheel flange. Installation replaces the wheel's outer ring and is secured using the original wheel screws, allowing the wheel to be rebuilt without altering hub geometry.

From a tuning perspective this part helps maintain tire alignment and reduces incremental slip between tire and rim during lower-speed technical driving or trail crawling tasks at scale. Use it when you need repeatable tire positioning after tire changes or when testing different compounds or inserts.
