Whow. Now this one is Super Huge. 4.5 is Awesome. This guy mounted on a 100mm Clown Shoe is and actual 4.25″ wide and is only able to fit on the Surly Moonlander front and rear. Big Fat Larry will fit on almost any Fatbike fork on any 65-100mm rim.
Ruda had 100mm Chopper US rims on his Expedition Pugsley with Endomorphs and was able to run a 9speed cassette with the 13 and 17 tooth cogs removed.
The Larry tread applied to a very large casing. This tire measures about 4.25″ on a 100mm rim! What does this mean to you? Float, float, float, my friend. Traction, Jackson. Larry tread provides good grab and steering in a multitude of conditions. For those of you looking for the maximum in traction and floatation, you have just found the mother lode. Available in 120tpi casing, in wire or Kevlar bead.
