The Mountain King UST is a fantastic all-mountain tire, especially when you run the 2.4" on both ends of your bike. For general purpose trail riding, pair the larger tire with the narrower 2.2" Mountain King UST in the rear, or for marathon racers who prefer a bit more speed, with the lower-knobbed X-King 2.2 UST as the back tire.

Continental revised the UST Tubeless Mountain King tread pattern so that it's more open, with stronger, taller side knobs for more sure-footed cornering, especially on hard pack. The tread is made from Black Chili Compound rubber, where tiny particles of carbon are added to the tread. This allows the tire to conform to the ground more readily, aiding both wet and dry grip. And because it's a UST tire, the Mountain King can be run without a tube, with or without a sealant, and has a special bead specifically designed to be paired to UST rims for a perfect seal every time, all the time.

Important: Although you can also run a UST tire on a non-UST rim, you won't achieve the same level of sealing because the rim won't be designed to wed with the tire bead as readily; there are conversion kits that allow you to turn a non-UST rim into a tubeless-ready setup, but they do nothing to change the design of the rim edge, which is the key UST innovation.

Another point: Running the larger volume 2.4" tire is an ideal match for all-mountain riders who need the added protection of sealant in places with a persistent threat from thorns or baby heads (or both!), and for those who also want the extra cushion that a bigger-volume tire provides.

The Continental Mountain King UST tire comes in a 2.2" and 2.4" width and has a 26" diameter. The tread is made from Black Chili compound rubber. The casing features 3 plies equalling 330 TPI under the tread and sidewalls. The UST bead is foldable and the tire is black on black. Claimed weights: 2.2" is 820g, 2.4" is 880g.
