For cyclists are looking to expand their cycling horizons. That includes roads that may not be suited for normal road tires. Our GravelKing tire solves that problem. Four widths to suit any rider's tastes. Natural rubber compound, puncture protection breaker and a special low rolling resistance casing make the GravelKing a go-anywhere tire. The Plus version offers even greater puncture safety and stability; this is made possible by a ProTite insert in the side wall and a circumferential nylon protective belt. Made in Japan - this is what distinguishes this and over 90% of the other Panaracer tire assortments. This ensures outstanding manufacturing quality using the most advanced materials.
