Constructed from a thicker 3 mm butyl compound and fitted with a TR-4 (standard) valve stem, this 100\/100x18 tube is designed to handle impacts, thorns, and gritty terrain better than standard 1.8–2.5 mm tubes while remaining compatible with common 18-inch rims.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this thicker tube improve durability on rough trails?\u003c\/h3\u003e\n\u003cp\u003eThe increased 3 mm wall thickness gives greater resistance to punctures from rocks, thorns, and pinch flats, reducing the chance of roadside failures.
