The Panaracer GravelKing SK Tubeless Tire is a shop-favorite for a myriad of reasons. Starting with Panaracer’s ZSG Natural compound, the GravelKing SK (or small knob) is imbued with low rolling resistance on smooth roads, a quiet ride (not usually the case with most knobby tires), and strong durability. The casing is tubeless-ready, but can be used just as easily with tubes. Perfect for any bike looking to add some cornering confidence in loose gravel and dirt, without sacrificing rolling resistance on the tarmac.
What’s the GravelKing SK gravel bike tire like in use? They measure true to size, feature a folding Kevlar bead, and loosen up a bit over time (they’re a bear to get on initially). Grip is excellent over loose dirt and gravel, and they don’t drag at all at lower tire pressures. Cornering is good thanks to those big knobs on the side; they release predictably when grip is lost. At just $50 for a tire, they’re one of the best-balanced gravel tires on the market, and great choice for any all-road or gravel bike.
The Panaracer GravelKing SK Tubeless Tire is available in both a black or brown sidewall, in 700c and 650b (27.5″) wheel sizes. 700c is offered in 35mm to 43mm wide tires, while the 650b tire is offered in a 48mm (1.75″) width.
