A tire that functions only with an inner tube to maintain tire pressure as defined by ISO 4223-1. The standard bicycle tire is designed for use with an inner tube to retain tire pressure. The inner tube serves two purposes: maintaining tire pressure and applying pressure on the bead of the tire against the rim hook and sidewall to keep the tire securely in place.
