The ultimate off-grid tire for sloppy mud, sand, and loose rock. The Protocol RCG-4 utilizes aggressive, widely spaced lugs that shed sticky loam and mud. Designed to bridge the gap between adventurous gravel racing and mixed trail terrain, this tire thrives in shifting, unpredictable conditions like mud, sand, and steep, loose rock. Wrapped in full bead-to-bead puncture protection, it gives you the confidence to tackle everything from singletrack, OHV roads and off-camber loose rock without fear of sidewall tears. 

The RCG-4 features an aggressive, wide-spaced knob profile utilizing fewer, but significantly larger, lugs than our RCG-3 model. This intentional spacing prevents dirt and sticky loam from packing together and caking the tire. In sloppy conditions where other tires might clog and lose traction, the RCG-4 actively flings mud away, ensuring reliable bite and uninterrupted momentum.
