Mr Tuffy XL-Series Tire Liners for Fat-bikes

mr-tuffy-fat-bike-linerMade of durable, lightweight urethane, Mr. Tuffy tire liners are now available for fat-bikes and provide a protective layer between the outer tire and inner tube. Urethane has a property which makes it very elastic. When a thorn or piece of glass attempts to penetrate the Mr. Tuffy liner it comes up against a surface that is both hard and elastic. The object pushes against the surface which gives way while resisting initial penetration.

  1. I wonder if these would be enough to cover up grip stud auger threads? Trax Fatty’s didn’t quite have enough tread depth for studs, so they poke through a bit. Winter flats suck.
