My truck is in the ditch!

:confused3:Someone could resolve this argument my taking a tire off one side of their dually truck and see what side gets stuck first! :cool2:

The two sides are connected. So if one side gets stuck wont the other side also get suck? or are you just anticipating the truck will go in circles?

Hmmmm. That seems to be a small problem:laughing:

These are the four trucks Toyota sent across Antarctica. They were accompanied by tracked vehicles.

As I said, it depends on if the snow is packed, if there is ice and if you want to float on top, or dig down to get traction.
In that case, they wanted to float on top of the snow/ice, not dig down, so they wanted wide flotation tires. It looks like they used Mickey Thompson Icepack Tires (per: World record holding Toyota Tacoma Polar Expedition goes to auction )

From another thread:

Wide, smooth tires of the proper compound for the conditions work better on common hard, dry road surfaces because with a relatively constant amount of friction per unit area you'll end up with more friction with a larger area. With wet surfaces or with snow and ice that has the potential for creating wet surfaces you need adequate load to break the water film between tire and road. With a large enough contact patch for the load you can glide easily on water, which is what some people like to do at the beach with 'skim boards'.
So, wide smooth tires don't 'fail gracefully' when confronting water. Grooves and lugs in tires create tread blocks to displace water and create higher loads per unit area, and siping is often needed when the tread block contacts the road. An example is with mud tires with large smooth tread blocks as it can do well in snow but on ice they can be just slightly better than slicks. As it gets colder traction on ice increases, but since you know that eventually water will form on the surface you want to be careful about too large of a contact patch.

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

Here's another deep snow vehicle.

I did that on my WRX as I saw a Norwegian study that showed they were slightly better.....But in return your dry and wet road performance sucks - so now I stick with stock sizes.

How did they solve this problem "back in the day?" Mount tractor tires to a Model A.

I think that model A has an edge though, there is a chain towing it along!

That chain was used to pull a dually out of a ditch!!!!

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.
