Tubeless Ready (TR)

Zleen’s Tubeless Ready (TR) casing is designed for a perfect, airtight fit—thanks to precisely shaped beads and an optimized bead diameter that lock securely into the rim. Thanks to advanced calendering technology and a special rubber compound, air permeability is drastically reduced, ensuring long-lasting pressure retention. Simply add a sufficient amount of tire sealant to activate the tubeless system. For maximum performance, we recommend combining it with Zleen Seal Pro tire sealant, high-quality tubeless valves, and high-quality rim tape.

120 TPI

The 120 TPI (threads per inch) casing offers a professional, high-strength, and elastic construction designed for race-level performance. Thanks to a finer, denser weave, this casing delivers exceptional handling and grip, quickly adapting to uneven surfaces when cornering and when applying brakes. At the same time, the 120 TPI construction ensures excellent grip during acceleration, making it
the perfect choice for racers seeking ultimate control and performance.

Bead-to-Bead (B2B) Reinforcement

Bead-to-Bead (B2B), developed for the toughest rides, wraps around the entire casing—from the bead to the tread—providing robust protection against cuts, punctures, blowouts, and impact damage. This full-coverage reinforcement is a hallmark of Zleen Pro tires, whose reliability is trusted by competitive riders on rough terrain, rocky trails, and in extreme conditions.
