if you have to run them id run them just on the front first so you will be able to steer and if you have to id toss a set on the back then if you need more traction

For the trails I think I'll just air down a bit.  Don't think it will be a problem. On the road, traction in the rear could be a serious issue for me.  I have an aluminum flatbed that weighs like 3 pounds.  Even on flat ground on snow in 2wd my rear (w/detroit)  always tries to catch up with the front     I'm really worried about my rear slipping out at higher speeds and puttin me in a ditch. (I know it sounds pessimistic)  I think I might need to pickup a set for front and rear.  Prismo told me he uses ones that have little pieces of metal (welded on the chain) for better traction? Anyone know where I can order a reasonably priced set.  I dont think many places in MO would sell them
