There's No Bikes Like Snow Bikes

If you ride in a wide range of winter conditions, The 45Nrth Dillinger 4 is one of the best winter fat bike tires for mixed conditions, thanks to its balance of speed and traction to help you stick to your line without slowing you down. And with optional studs, you'll never slip, slide, or lose control on ice.

45NRTH tires are designed for extreme winter cycling applications. They 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.

Great all around
by Anonymous

I�ve ridden them now on sand, dirt, fresh snow, and groomed snow fat bike trails. They are a great do it all tire. Roll much faster than the Vee Avalanche they replaced! Ran at 5 psi tubeless with fatty stripper rim strips on groomed snow single track and had awesome grip and surprising high speed. So much fun.
