Panaracer has debuted a gravel tire with all of the benefits of the GravelKing SS, but with an added bead-to-bead layer of the brand's ProTite puncture material for added protection. The GravelKing SS Plus sees an all-new tread pattern with a smooth, diamond-patterned center and more aggressive side lugs so you can benefit from staying power on corners. Panaracer incorporates supple 126 TPI casing with nylon, puncture-resistant belt and the brand's proprietary ZSG compound. For all of the twists and unexpected turns gravel riding throws at you, the GravelKing SS has your back with durability and lasting speed.
