Snow is finally here

Fantastic pictures! Nice to lok at from inside a nice warm house. By the way, do you have a heater in that Pinz?

Andy, believe me when I say it was very warm when I was stuck. It was lots of work to put the chains on.

I have the standard heather in my Pinz, but it is in good shape plus I'm dressed to survive winter.

And they say that this storm originated from Texas. Thanks Andy, and you all from Texas to have sent us such a nice Christmas gift.

Great idea to put that cover on the intake. I am sure it was cold enough for the engine. Does it (cover) help with the standard heater? I put glas-fiber with foil wrap on the heater pipes and it does help a bit.

Good day all,

Morris the cover on the front was the idea of Karl Portmann from Pinzgauer Canada as I was complaining to him about poor idles when I was riding in heavy snow fall. It is working great so far and the engine is running a bit warmer witch help the heating system quite a bit. The heating system is doing enough a good job that all the windows and the windshield are clean of frost and condensing as you can see in the pictures. Remember that I’m riding in temperature below -5 Celsius; I don’t think I would use the front cover on highway or in warmer temp.

Happy Greeting Season to you all…

Does one air down for snow? I seem to remember several different versions of the method of driving in snow, and I thought that narrow tires were better. That sort of blows the idea of airing down, if less air means wider footprint.
Opinions are welcome.

Good day all

When I drive off road I always air down the tires and I can see a very big difference in tire performance especially on snow. Narrower tires are the best for snow. I think that the tire that are air down make some kind of a scoop under it and it help it float some way.

Just remember, don’t do as I did. Put the chain on before getting stuck, a lot easier than after.

Airing down in snow is a good idea, particularly with narrow tires.
With typical big/wide off-road tires, airing down increases your "contact" patch in width as well as in length (length being the contact patch measurement in line with vehicle movement). Look at just about any big off-road tire and you'll rarely see the tread wearing equally across the entire pattern. Unless the owner is very precise with his tire pressure, the tread crowns, and only a portion meets the road surface, except when aired down.
With a narrow tire, even at street pressure there is less crowning, and the tread tends to wear more evenly. When aired down, the width of the contact patch changes little, but the length increases. It would seem to me you have more force aligned for forward motion with less flotation. I'm no engineer, but I DID grow up in NE Iowa and did LOTS of snow driving, so this is all armchair theory.
