Tube Type

Tube-Type tires have been the most common, and most recognized, for years. They have a hook bead, require a properly sized inner tube, and mount to rims with hook beads. The inner tube maintains inflation pressure while holding the tire against the rim to keep it safely in place.
American Classic Tube-Type tires follow current global E.T.R.T.O. standards for clincher tires and clincher rims. They require a rim that includes a hook bead. For more information on tire and rim compatibility, see our Tire – Rim Compatibility page.
