The Panaracer GravelKing R-Line 700x40 gravel tire is designed for pavement, hardpack, and fast all-road routes, combining a minimal file tread for pavement, hardpack, and fast all-road riding and a clearly identified tubeless-ready folding configuration. This Black/Amber variant gives riders the exact size, construction, and finish needed for a confident replacement choice.

The current-generation construction combines ZSG Gravel Compound with lightweight TuffTex R casing and BeadLock bead design. The 700x40 casing and tubeless-ready folding format help shoppers confirm compatibility before installation, while the tread design is matched to pavement, hardpack, and fast all-road routes.
