Experience I have is driveing in winters that last 5+ months over the last 10 years everything from Ice, Slush, Deep Snow, Wet Snow, Dry Snow ect here on a dailey basis not for a week end sking trip or a drive up to the mountains. Dulleys get no traction cause they spread the weight out to much and can't bite in. If I was to go into deep snow with them the resistance would make it hard to roll also. Now that all depends on your weight also. I am talking about dulleys on pick ups(lbs per sq inch again). I did say if it is deep packed snow or hard deep snow you want to stay on top if you can and narrow ones will break the crust and bury. But how often to you want to drive off across the drifts in the middle of nowhere with a rig? Good way to have your truck spend the winter there. 99% of the driving is not on that kind of snow so you need traction to bite in and pull. You have hills that require tork to get you up not just floating. If your tires can't bite in they will spin that is why Sand Rails go up dunes under high HP spining the tires all the way with flaps to throw the sand and float on the top if they can so as they slow down they sink. Wet sand is different it is packed and does not churn the way dry does. The only reason dulleys dig in is because they are spinning and throwing out the dirt out from under them instead of having enought weight to adhere to the surface push in the tread and role forward. The big tires on my Jeep will just spin it around easy if the surface is slipery like having a sled under each corner. Same with my tractor I have very wide agressive tires but no way will it pull as good as my neibors who has ones twice a narrow and the same tread. I weigh more and have more HP also. If you drove on winter roads all the time you would under stand what I am talking about but remember you live in So. California where the weather is nice and warm. Why is it that the citys get a little snow or ice they all start wrecking? Heck I have had packed ice and snow on my roads for 6 weeks and haven't put chains on the school bus yet and it is 2 wheel drive but I garentee you if I don't put my 1 ton Dulley in 4X4 it won't go near as far as the ford ranger in 2 wheel drive with the regular narrow winter tires on the back. I have narrow aggressive tires on the bus and it even has duels but, it also weights more and softer springs to keep bounce from lifting the tires off the ground and lessing the weight even more when I need it on the ground.
