The GravelKing Slick comes very close to a conventional road tire. However, thanks to the fine tread structure, available widths, and better puncture protection, it is significantly superior in terms of grip, comfort, and safety. The rubber compound boasts a specific material formulation for gravel, starting with Panaracer's patented ZSG (Zero Slip Grip) material. ZSG guarantees excellent resistance to temperature and weather conditions, offers low rolling resistance, and consistent grip across a wide range of temperatures, from near-freezing to scorching heat. TuffTex is a revolutionary structure developed exclusively for GravelKing tires. Thanks to its soft casing and high thread count, TuffTex ensures long-term durability and provides precise puncture protection. This unique compound guarantees an exceptionally smooth ride and offers the lowest possible rolling resistance on a GravelKing tire. BeadLock: The tire bead adapts to different rims (including hookless ones) and in most cases can be mounted with a standard floor pump. Panaracer Gravelking tires are manufactured in Japan by experienced technicians using the most advanced materials. This guarantees exceptional production quality and performance. Note: For installation, Tubeless Ready tires require rims/wheels compatible with Tubeless technology, Tubeless valves, Tubeless rim tape, and sealant. Puncture sealant is not necessary for UST Tubeless tires, but is recommended due to increased puncture protection. Installation of Tubeless tires is not always easy and should only be carried out by qualified personnel.
