Leave the beaten path behind with the gravel-crushing confidence of the Panaracer GravelKing Tire. Optimized for adventurous tours and gravel grinds, the GravelKing is reinforced with an Anti-Flat casing that protects it from inconvenient flats across remote areas where help is a long way off. The ZSG Natural Compound and grippy tread pattern promote confidence along off-road stretches and gravel roads--all without compromising rolling efficiency when you encounter some asphalt on the way back to town. Please note, the original GravelKing isn't the best option for muddy off-road stretches, as Panaracer has a mud-specific version of this tire for these sloppy conditions.
