The Panaracer GravelKing SS 27.5x1.50 / 650B x 38 bicycle tire is designed for all-road riding across pavement, hardpack, and light gravel, combining a fast semi-slick center with shoulder tread for added cornering support.

The GravelKing SS uses a fine center tread for efficient rolling and more pronounced shoulders for control on unpaved turns. Its ZSG Gravel compound, TuffTex casing, and BeadLock construction support versatile mixed-surface use. This variant is tubeless ready for use with a compatible rim, sealant, and valve.
