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.
