Panaracer was ahead of the game with their famed GravelKing tire. The SK model was developed to meet the constantly evolving needs and requirements of gravel and adventure riders. The Tubeless compatible options added greater diversity of use, with the benefits of low pressures. With it&';s size options and unique tread design, not to mention Panaracer&';s mastery of supple, high performing tires, the GravelKing SK TLC is built for speed, traction, durability, and grip. The tread pattern is the first thing that draws your attention to the SK. With a large central zone of low profile small knobs, you can almost feel the grip and adherence you need on firmer, rocky surfaces. The ZSG natural rubber compound Panaracer uses offers great feel and overall grip, but with lower rolling resistance than most. You can still carry speed on pavement with this tire, and not suffer terrible wear. The side edge of this relatively flat-shape tire has a nearly continual directional line tread, but it is broken up by a shorter version that wraps the edge for traction in softer material and provides some bite into softer corners as well. The genius of the tread pattern is how well it hooks up off the pavement, matched with how well it rolls and corners on pavement. Life and wear will be best off smooth pavement, thriving and holding up to gravel and mixed trail use.
