The GravelKing EXT is built for the most extreme conditions you can throw at it. With a tread design tailored to work best in muddy and sloppy conditions, the EXT will keep gripping through the absolute worst of it. The entire tyre is protected by our ProTite Shield to ensure high strength puncture resistance, whilst the ZSG (Zero Slip Grip) compound offers low rolling resistance for an excellent ride and enhanced wear resistance. Part of our hugely popular GravelKing range, the GravelKing EXT TLC is the tyre designed specifically for the loosest gravel and mud you can find.
