At 50mm, this is the widest GravelKing SK available for 700c wheels, and the extra volume changes how the tire performs on rough terrain. More air means you can run lower pressures without risking rim strikes, and lower pressures translate to a larger contact patch and better damping over rocks, roots, and washboard surfaces. If your gravel bike has the clearance and you're spending more time on chunky surfaces than smooth hardpack, the 50mm width earns its keep.

The SK tread pattern sits in the middle of Panaracer's GravelKing range, more aggressive than the smooth-centered SS but less knobby than the new X1. Five rows of tightly spaced square blocks form the center section, providing consistent traction without excessive rolling resistance on hardpack. The shoulder knobs are taller and more widely spaced, engaging when the tire leans into turns and providing grip in loose conditions. This balance makes the SK a genuine all-rounder—capable on pavement connectors but genuinely useful when the surface deteriorates.

Construction follows Panaracer's current GravelKing platform. TuffTex is the casing structure, combining a high thread count for suppleness with bead-to-bead puncture protection that extends through the sidewalls. ZSG Gravel compound maintains consistent grip across temperature swings, performing the same whether you start in cold morning air or finish under afternoon sun. BeadLock is the bead design that simplifies tubeless mounting on both hooked and hookless rims—most riders can seat these with a floor pump rather than needing a compressor.... Read More
