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. Don't let the semi-slick tread fool you, it has soft compound rubber which grips well on gravel and rolls fast on tar.
