    Introducing Pro-Line’s next level performance, CR Compounds, specifically engineered to suit today’s high-grip carpet tracks! With the exploding popularity of 1/10 Carpet off-road the last few years, Pro-Line set out to raise the bar on carpet tires with our CR3 (Medium) and CR4 (Soft) compounds. Tested by Pro-Line’s factory team of drivers, CR provides improved grip and consistency across many different styles of carpet. CR4 has already taken its first victory at the 2021 US Carpet Off-Road Championship in Cleveland in the hands of Aydin Horne, with Ryan Cavalieri making it a 1-2!
