236964 18 Inner Tubes with Steel Center Valve Suitable for 180 55 1

Metzeler heavy-duty inner tubes are engineered from non-porous butyl rubber, a material specifically chosen for its ability to maintain consistent air pressure over much longer periods than traditional natural rubber. These 16-inch tubes are designed to withstand the weight and demands of Harley-Davidson cruisers, providing a reliable foundation for spoked wheel setups. This specific range offers various valve configurations, including moulded rubber off-set, steel off-set, and steel center valves, ensuring compatibility with different rim profiles and stem hole locations. By choosing Metzeler, riders benefit from decades of engineering focused on tire performance and safety, resulting in a tube that resists thinning and air loss under heavy loads.
