Panaracer GravelKing SS R Tire - Tubeless, Folding

The Panaracer GravelKing SS R is a race-oriented gravel tire designed for riders who prioritize speed and efficiency on hardpack, pavement, and fast gravel. Sitting between a full slick and a more aggressive tread, the SS R uses a semi-slick (file tread) center to minimize rolling resistance while still maintaining enough side tread for confident cornering.

This “R” (Race) version is built with Panaracer’s most advanced casing, making it lighter, more supple, and faster than standard SS models. The result is a tire that delivers a noticeably smoother ride and improved energy transfer—ideal for gravel racing and high-speed mixed terrain.

A key feature is the TuffTex R casing, which provides bead-to-bead puncture protection while remaining extremely flexible. This combination improves ride quality without sacrificing durability. The ZSG Gravel compound ensures consistent grip across a wide range of temperatures and conditions, making it reliable for both dry and variable weather riding.
