With a low-rolling resistance and a semi-slick center tread, Schwalbe's Thunder Burt delivers excellent grip in dry, hardpack conditions. The outer lugs grab in the turns while the many small center lugs provide just enough to hold your line. RaceGuard puncture protection helps prevent flats while maintaining a low weight, while the SnakeSkin option gives better sidewall protection.

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.
