Using your 45NRTH Dillinger 4 tire is a breeze. First, make sure it's properly installed on your fat bike. You can use it on snowy and icy trails for a great winter riding experience. When riding, take advantage of the center tread for fast rolling and the side lugs for better cornering. As for maintenance, regularly check the studs. If you notice any studs are loose or missing, you can replace them. Remember, the replacement studs and the stud insertion tool are sold separately. Also, keep the tire clean and check the air pressure regularly, aiming for the recommended 20 PSI. This will help ensure a long - lasting and high - performing tire.
