Born on the World Cup circuit and built for those who refuse to slow down, the Schwalbe Tacky Chan is the fastest downhill tire on earth, now available in Radial construction. With 17 World Cup victories in just two seasons and Amaury Pierron's 2022 overall title, the Tacky Chan's race pedigree speaks for itself. The Radial carcass threads are woven closer to 90 degrees rather than the conventional 45, creating a 30% larger contact patch at the same air pressure for more grip, more damping, and more control on aggressive lines and high-speed descents. Exclusive to the 2.5" width, the Radial construction is paired with a refined tread featuring wider-spaced knobs and a tighter shoulder gap for improved intermediate cornering behavior, especially when run up front. Features Radial carcass laid up at 90 degrees delivers a 30% larger contact patch at the same air pressure for more grip, more damping, and more control Redesigned tread pattern with wider-spaced knobs and a reduced shoulder gap for improved intermediate cornering behavior, especially when mounted on the front wheel Open shoulder area provides direct feedback and improved self-cleaning lugs Long braking edges allow for later braking points coming into corners Ramps on center lugs for optimal rolling characteristics E50 rated tires are designed to withstand the additional weight and forces of e-bikes Casing & Compound Options Gravity Pro Radial Originally developed for the Downhill World Cup, the Gravity Pro Radial delivers maximum stability, full puncture protection, and uncompromising precision. Six carcass plies under the tread and four on the sidewalls provide the rigidity and protection demanded by the world's fastest downhill racers. The same spec trusted by World Cup pros, now available to you. Trail Pro Radial A slightly lighter alternative to the Gravity Pro, the Trail Pro Radial brings Radial performance to the Tacky Chan in a more trail-friendly package. Three carcass plies under the tread and two on the sidewalls keep weight down while still delivering reliable puncture protection, ideal for riders who want World Cup-derived Radial performance without the full gravity setup. Soft The versatile, high-performance choice for riders who demand more grip without sacrificing durability. Delivering excellent damping and superior grip across all weather conditions, Soft is a natural upgrade for enduro, downhill, and trail riding, and an ideal match for e-MTBs where consistent all-weather traction is essential. Ultra Soft Completely redeveloped for the 2026 Downhill World Cup, Ultra Soft is engineered for riders who demand maximum traction when conditions are at their worst. Delivering exceptional damping and year-round grip through roots, rocks, and wet terrain, it's the trusted compound of World Cup downhill athletes. Best suited to the front wheel or rear in lift-assisted riding where grip matters more than rolling speed.
