CRC Pro-Cut 1/12th Yellow compound on CRC high Roller 38 mm wheel. Med-soft shore, long-wear, high grip, softer than grey, harder than white. Great tire for 1/12th stock and modified!

This is from the Japanese-made white/yellow/grey/black family of foam rubber.  A very light weight foam that resists carpet fiber collection as well as grip “pick-up”. This family of rubber is good at repelling loose carpet fibers and also tends not to get sticky as the run goes on. This compound wears faster than Pink/Purple and the Greene/Blu family of rubber.
