Sandworm ( 26″/ 27.5″ Fat Bike )[RETIRED]

  • What tire size should I put on my Sandworm?

    This depends on what you primarily want to ride on with it. If you have a trail bike you are perfectly happy with and are just looking for a bike for snow, sand and unusual terrain, start with a 26" wheel with 3.8 to 4.0" wide tires. While 29+ and 27.5+ are fatter than the average MTB tire, they don't offer the floatation needed for optimum rolling over snow and sand.

    If you are looking a more confidence inspiring mountain bike, we would first recommend 27.5"+ (650b+). 27.5+ gives you much more traction than a standard 29" x 2.4" tire (since you run them a lower pressures you can expect at least a 50% larger contact patch). it is noticeably lighter and theoretically stronger than a 29+ set up.

    29+ is still a viable option, since (thanks to Surly) there are some good options for tires and wheels, though we think 27.5+ options will catch up by 2016.
