Schwalbe's Marathon Plus is legendary for durability and protection. Their nearly impenetrable 5mm-thick SmartGuard layer almost eliminates flats over the course of the tire's excellent, long life. Whether you're setting out on a cross-country bike tour, cruising on a tandem, or just want peace of mind during your daily commute, the Marathon Supreme is in it for the long haul.
