i would still think it depends upon whether going uphill or downhill, weight issues aside. i've only been to bear once, but not during skiing season. having gone up an extremely treacherous bad weather mountain in ruidoso, nm, i wouldn't have had the chains anywhere but on the front. i want the traction where the steering components are, and i'd rather be pulled up than pushed up, chain-wise. coming back down though, i might switch to the rears. good point on the weight distribution, jim. i did not know that.
