Panaracer positions the GravelKing SK R as their fastest gravel tire—the "R" designation indicating their most supple and lightweight casing construction in the updated GravelKing lineup. The SK tread pattern arranges five rows of square knobs between continuous outer ridges, balancing traction on loose surfaces with a smooth-rolling center section for mixed terrain riding. Where the standard SK prioritizes durability and the SK+ adds puncture protection, the SK R strips weight and prioritizes ride quality for racing and performance-focused gravel applications.

TuffTex R casing represents Panaracer's lightest construction, using a high thread count for suppleness while maintaining bead-to-bead puncture protection. The result is a tire that conforms to terrain at lower pressures without the lateral squirm that heavier casings can introduce. ZSG Gravel compound—formulated specifically for mixed-surface riding—maintains consistent grip across temperature swings, addressing the cold-morning-to-hot-afternoon conditions common in long gravel events.

BeadLock technology redesigns the tire bead for compatibility with both hooked and hookless rim profiles. The updated bead seats more reliably with a floor pump, eliminating the compressor dependency that plagued earlier tubeless gravel tires. Tubeless pressure rating tops out at 60 PSI, appropriate for the lower pressures that gravel riding demands. The black tread paired with brown sidewalls delivers the classic aesthetic that has become synonymous with the GravelKing line.... Read More
