From light winter trail riding to commuting, Kahva allows you to carve your way through winter with steel carbide studs as well as single, double and triple siped lugs.

  • Siping on center and side lugs allows them to conform to terrain better for increased grip in any riding conditions
  • 252 concave carbide studs provide traction in the iciest conditions
  • Directional lugs provide low rolling resistance while offering excellent braking traction
  • Tubeless ready (60tpi)
  • 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 pre-mature casing wear and stud loss.

Audio: (chill inspirational music) Video: A man rides a fat bike quickly through a sunny, wintery, and wooded environment. "45NRTH Kahva" text is overlaid as he rides and kicks up snow. Audio: [Narrator] The Kahva is our mountain bike sized commuting tire. It’s designed to take on the worst of winter and still deliver riders to their destination. The Kahva has three features that provide riders with traction and control in slick conditions. Video: A rotating Kahva tire is in view. Audio: First, the Kahva has siping across the entire tread pattern from side lugs to center lugs. This siping gives more biting edges on the snow and slick surfaces. Video: The view zooms in and “Siping: Increased grip on ice & snow.” text is shown to highlight the center and side lugs with multiple parallel grooves. Audio: Second, the lugs are spaced out to dig through soft snow down to firmer terrain for traction. Video: “Spaced Lugs: To dig through soft snow.” text is shown to highlight spacing of the side lugs. Audio: Lastly, the Kahva has carbide-tipped studs on the side and shoulder lugs, to provide grip on ice. Video: “Carbide-Tipped Studs: For grip on ice.” text is shown to highlight studded side lugs. Audio: Kahva also has ramping on the leading edges of all lugs to increase rolling efficiency, especially on dry surfaces. Video: “Ramped Lugs: Increases rolling efficiency.” text is shown to highlight ramped edges on the bottom of each center and side lug to its siping or studding. Audio: Kahva comes in the following sizes and configurations. Video: View zooms out and “27.5 x 2.1”: 33TPI Steel Bead, (240 Carbide Studs); 29 x 2.25”: 33TPI Steel Beads, (252 Carbide Studs)” text is shown for sizing. Audio: (calm music) Video: 45NRTH logo and “” text is shown, along with Instagram, Facebook, and Twitter logos.
