45NRTH Dillinger 4 Tire - 27.5 x 4.0, Tubeless, Folding, Tan, 60 TPI, 168 Large Concave Carbide Aluminum Studs Black/Tan EA Tires

60 TPI tubeless-ready casing 168 Large Concave Carbide Aluminum Studs reduce weight and are bowl-shaped to provide more surface area and sharp edges for superior control and confidence on ice. We design 45NRTH tires for extreme winter cycling applications. We do not recommend this product be used with power assist bikes as the additional torque and system weight can lead to premature casing wear and stud loss. Always check with your rim manufacturer to verify rim & tire compatibility before assembly or use
