The traction isn't from the snow, the idea of the skinny tire is to cut thru the snow down to the bare road or dirt and find its traction.

If you are in a situation where you need flotation in snow, you better get a set of tracks!

When you buy snow tires on Tire rack, they suggest down sizing the width one size for best performance?.

I live near the Tire Rack's main warehouse. They have a test track out there. They didn't do much testing last year here due to very little snow. When it does snow, they do a lot of testing. Neat to watch. They also do a lot of testing in summer, and the entire track has a spinkler system for wet testing.

Here's a link to google maps satellite view of their facility....

Probably the wide tire floatation concept versus skinny tire digging in and biting more depend on numerous variable conditions. As long as the floatation tire is actually floating on the surface, things are fine and dandy, but once they break through the surface and dig down in, all the physics change and things suddenly aren't so rosey. The two vehicles pictured above seem to indicate that both concepts could work quite well, but something halfway in-between (a status which duallies can fall into under certain conditions) may not.

Yep, plenty of variables.

Traversing snow off-road vs. pushing a 1000# plow plus 1000#+ snow load down a track are very different applications.

Thats a winch truck for moving skid type equipment. The tires are so large due to the very heavy loads they are able to move around. When we would move a drilling rig in or out of a location, a winch truck was used to move various pieces around location for cleaning or assembly. There is a winch or most likely two right behind the cab of that truck and a tail roller on it. They drop a loop of heavy cable down around the end of the skid mounted equipment, pick it up and pull it up over the tail roller until it heavy balances. Then they drive to where they want to put it and slack the winch off. Really neat to watch!

100% correct. I owned an F350 4x4 crew cab dually for 10 years. I could get by in the snow but it was always a handful with the rear tires tracking in new snow versus the front tires. I ran road tread tires on it anyway but still got by OK. I don't think that combo would work well in deep snow without added weight in the rear and more aggressive tires. We may get some snow this weekend. I am hopefully looking forward to taking out my 2500 HD 4x4. It has 17" rims with a fairly aggressive tire.

You can get by driving a dually like that, but around here it's not much fun. Neighbour has a DRW 2wd Dodge Cummins he drives all year. He keeps it because he pulls a race trailer during Summer with it.

On secondary (last to be plowed) roads around here I'll see him slowly churning through snow with it. I'm not exaggerating when I say that if I could magically find a perfectly dry piece of pavement to stand on in front of that truck in that snow, I could easily hold that truck still myself. And nobody ever confuses me with the Hulk :laughing::laughing:. On that same snow, my olde RWD Volvo wagon has no issues at all, running just a basic snow tire. And, that is just moving the truck by itself - once you starting pushing snow w. plow, you need to be able to put a lot more power to ground.

I grew up learning to make just about anything work in the snow. A good friend once rented from Rent A Wreck back when (it was a Pinto !) and drove from Toronto to Ottawa (about 300 miles) at Christmas on almost bald tires. That took a lot of skill, as he spent a good portion of the trip correcting sideways drift. Knowing how to make poor equipment behave well is a useful skill, but as I've gotten older I try not to go there if I have any other options :thumbsup:.

It's all about knowing the limits of the equipment and tires - worth knowing on any platform. Often, the vehicles I see the farthest (unintentionally) off-road near our high speed roads in Winter are 4wd trucks and SUVs - you can exceed limits on anything. Even tanks can get stuck.
