Anyone running 2 "regular" MTB tubes (26x2.5) per tire in their fat tire set ups?
The idea - drill 2 offset holes in fat rims for tubes, install tubes and inflate.
The reason - if one tube goes flat, you could still get home without having to replace tube.
Not saying I am going to do it, but I have had to repair a flat in the winter and it is a pain in the butt.
