The Michelin Pro5 TLR tire runs tubeless with sealant or tube-type with an inner tube, and it's compatible with both hooked and hookless rims, so the tire adapts to the wheel setup rather than the other way around. A Gum-X compound and 3x120 TPI casing keep it fast and supple without giving up the puncture protection of the Bead-to-Bead Shield across the crown and sidewalls. What Our Gearhead(R) Experts Are Saying:"I've run this on a mixed-surface trip that hit rough gravel and embedded rock without a single flat. It stayed comfortable and fast-rolling across every pressure I tried, well past what an endurance road tire usually gets asked to handle."
