Using this 45NRTH Dillinger 4 tire is easy. Just mount it on your 27.5 x 4.0 fat bike as you would with any other tire. When riding on snowy or icy terrains, take advantage of the studs for better traction. When cornering, the side lugs will help you stay in control. Note that replacement studs and a stud insertion tool are sold separately, so keep that in mind if you need to replace any studs. For maintenance, after each ride, clean the tire with a mild soap and water to remove dirt and debris. Store it in a cool, dry place away from direct sunlight to keep the rubber in good condition.
