here's a great idea for your next tractor Bob
the rollagon tires run such low air pressure you can drive over the top of a human with out hurting them
they are building ice roads across the tundra on the north slope. the rollagon tires run such low air pressure you can drive over the top of a human with out hurting them
I'll hold your beer. You first!!!
Bob I think what you want is Pelosi under a freight train as for traction at -40 the ice and snow will give you some pretty good traction as long as you don't spin the tires, almost like sand. the other thing to remember is all tread does is dig you in deeper, it will also increase your weight in small areas the reason for those bag type tires is not to disturb the exposed vegetation, un like Canada where they cut corridors for ice roads here in Alaska when the road melts there is to be no signature left as to where there was a road.I'll hold Nancy Pelosi's beer. She can go first
