Using the 45NRTH Dillinger 4 tire is easy. First, make sure your bike is compatible with a 27.5 x 4.0 tubeless fat tire. Install the tire following the standard tubeless installation process. If you want to use the studding feature, insert the studs using the separate stud insertion tool. When riding, take advantage of the center tread for fast straight - line rolling and the side lugs for better cornering on snow. As for maintenance, check the tire pressure regularly and keep it at 20 PSI. After riding in harsh winter conditions, clean the tire to remove any dirt or debris. If a stud comes out, you can replace it with the separately sold replacement studs. Be careful not to over - inflate the tire as it may affect its performance.
