The 45NRTH Dillinger 4 is a fast-rolling studded fat bike tire built for confident traction on ice and packed snow. This premium 120 TPI version pairs a supple, high-thread-count casing with 168 Large Concave Carbide Aluminum studs — delivering more traction and grip than the standard carbide steel stud version. Tightly spaced center tread rolls quickly, while taller braced side lugs improve cornering in snowy conditions. Tubeless-ready with a folding bead.
