Panaracer GravelKing SK Tire - Tubeless, Folding

The Panaracer GravelKing SK is one of the most established and widely used gravel tires, designed to deliver a strong balance of rolling efficiency, traction, and durability across mixed terrain. It’s built as a true “do-it-all” gravel tire—fast enough for pavement and hardpack, but with enough tread to stay controlled on loose surfaces.

The SK (Small Knob) tread pattern uses tightly spaced center knobs for low rolling resistance, paired with more aggressive shoulder lugs for cornering grip. This gives it a predictable feel when transitioning from pavement to gravel, making it especially effective on hardpack, dirt roads, and light-to-moderate loose terrain.

A key feature is the ZSG (Zero Slip Grip) gravel compound, which maintains consistent grip and performance across a wide range of temperatures and conditions. The TuffTex casing adds bead-to-bead puncture protection while keeping the tire relatively supple for improved ride quality and efficiency.

The tubeless-ready design allows for lower pressures, improving comfort, traction, and flat protection—especially important for gravel riding.

Key Features / Technical Details

• Semi-knob tread pattern for balanced speed and off-road grip
• Tubeless-ready (TLR) construction for lower pressure and improved comfort
• ZSG gravel compound for consistent grip in varied conditions
• TuffTex puncture protection for durability without excessive stiffness
• BeadLock design for improved tubeless compatibility and retention
• Folding bead construction

Technical Specifications (varies by size)

• Weight (example):
  • 700x30: ~330g
  • 700x35: ~420g
• Max pressure (TLR): typically up to ~60 psi
• Casing: high thread-count with bead-to-bead protection

Rolling Performance

• Moderate rolling resistance (faster than aggressive gravel tires, slower than slicks)
• Strong balance of efficiency and traction
• Excels on hardpack, pavement, and mixed gravel
• Less ideal for deep mud or very loose terrain

The GravelKing SK is ideal for riders who want a reliable, versatile gravel tire that can handle a wide range of conditions without specializing too heavily in one direction—making it one of the best all-around options for everyday gravel riding, training, and mixed-surface adventures.
