Continental 0100301 Trail King UST Tubeless 26 x 2.4 Foldable MTB Tire with Black Chili and Apex touts it"s own special blend of extra soft and tacky Black Chili compound. This special compound shreds the wet rocks, roots and mud like no Continental compound ever before. And unlike other soft compounds that go away quicker than the wind, this sticky one lasts. The sidewalls are reinforced with Conti"s proprietary Apex design. Apex is a unique sidewall treatment that places additional material just above the bead where it helps to reduce pinch-flatting, while also stiffening the sidewall to improve control under hard-cornering and in off-chamber sections. The King is stout with an oversized casing and puts a massive footprint to the ground for phenomenal control. The tire and rim form an airtight chamber. A tube is not necessary and pinchflats not possible anymore. Specs: Weight - 1100 grams; Recommended PSI - 45; Maximum PSI - 58; PU - 5.
