Description
A quality inner tube is critical to maintaining tire integrity, fuel efficiency, and ride safety—and Michelin’s engineering ensures all three. The overlap splice design positioned opposite the valve delivers superior strength and balanced performance compared to standard butt-splice tubes, reducing the risk of failure during aggressive riding or extended use. Whether you’re tackling technical terrain or logging highway miles on an 18-inch wheel, this TR-4 tube is engineered to keep pressure consistent and reliability high.
