The XR4 Team Issue TLR is Bontrager's answer to loose, rocky trails. It's perfect if you're looking for an aggressive tire that rolls decently, grips hard, and rages through any obstacle in your path. To achieve that, its cupped lateral blocks and long, buttressed shoulder knobs are dialed to hold your line when you're stuffing it into corners at speed. This Team Issue TLR version has a lightweight folding bead and supple high-thread-count casing to save weight and improve your connection to the trail for a more responsive, faster accelerating tire. Mount them up tubeless for an even more lively and reliable ride.
