Panaracer Tires is pleased to support Gravel Worlds with the GravelKing range of tires. Panaracer Tires was early an innovator in the gravel scene, and the GravelKing range is now known as the go-to option for mixed surface riding and racing. Competitors can choose between our GravelKing and GravelKing SK options. The SK, with more pronounced tread pattern and fast rolling shoulder knobs will give the most traction, but the slicker GravelKing will be the faster choice. Coming in a range of sizes from 23c-32c (GravelKing) and 26c-40c (GravelKing SK), Gravel Worlds competitors will find the right tire for their race with Panaracer.
