Some SUV manufacturers recommend leaving an all terrain tire on all
year around. Seems that the vehicle will tend to tip over less if
the tires can slide sideways when overcornered a bit.

I keep Michelins on mine all year round...the same thing that makes
them good in Sierra snow makes them good in unexpected downpours.
If I did more timber road or rocky driving would probably change
to a Pirelli Scorpion AT with the extra ply sidewalls. For
hard core rock crawling, I'd just change the vehicle.

Yeah, I use Michelin M+S and they are not only quieter than the
original Goodyears but help gas mileage and definitely have more
traction. With a bit more ice, the Michelin Pilot helps but
so does simply using brains. The heavy steel belted Michelin
and Pirelli tend to be quieter with better highway tracking
than the plastic belted radials.

Really really bad ice and/or packed snow. With a speed limit of
15-25 mph when attached. With limited slip and good tires, never
needed to use them in many many severe winter condition trips, but
always carry two sets.

A good set of chains for modern 4x4 with ABS would be something like
these:
http://www.scc-chain.com/Pages%20Tra...ucts/szlt.html

They still give a rough ride and have a very low speed limit [the
centrifugal force moves the chain outwards where it can damage your
vehicle] but excellent traction.

The nice thing about a real SUV is you normally have better clearance
to put them on. Also you should always carry a very still blade
shovel in case you need to remove ice/snow pack away from your
wheel wells in order to install chains.

A few feet of plastic fencing makes it nicer to drive onto for
installing the chains.

It would take some really severe snow to need them in the first place
though. As in snow deep enough to drag heavily on the underside of
your vehible.

Unless there is pack ice under snow, as long as the snow isn't deep
enough to drag on the body heavily, you should be able to keep moving
without chains in any good 4x4. If you want a safety measure for
hill descent, as long as you keep speed well down, I can't imagine
anything lower than a Wyoming blizzard that could stop a 4x4 with
enough power that is fitted with chains.

Never used them, and pass thru there frequently in winter.
You don't even need to carry chains in a genuine 4x4 with snow tires
except in the very worst conditions. And that snow is very wet and
sticky. See all sorts of Cute Utes stuck in the worst weather, but
rarely a Jeep unless the driver is an idiot.

Yes, genuine 4x4s don't really need them. I meant cars.

I80 is plain hazardous to cars during heavy weather. My old car was COATED,
including the windows, in frozen sand spray from the SUVs with snow & muds
around me. I had to get off the road several times to wipe down the
windows.

I carry a set of Z-chains for my 4x4, used them one and they did work
well. Was in some wet spring snow, and it was starting to freeze as the
sun went down. Had to pull 2 trucks up a steep hill, so I slapped on
the chains, at the time I was buried to the axles in deep snow and got
the chains on without having to move the vehicle:

http://www.4crawler.com/4x4/CA-4/TR_2001_04_21.shtml

The Z-chains are nice in that the cross links cross the tire diagonally
instead of radially so you don't end up with bare tire, then chain, then
bare tire, so you always have some chain between the tire and the
snow/ice.

Normally, just airing down the tires as needed for the conditons is
sufficient. I'll drop to 10-15 psi normally and have sone as low as 7
on my 33x10.50 tires (was at that pressure in the above photo).

I have a Tahoe Z71. I do not off road at all, but really enjoy going to
the snow. When the news says 'chains required', does that apply to 4wd
vehicles? I dont have chains, and always wonder if they are going to
turn us away.

Check your local laws. In many cases no, as long as you have snow & mud
tires, but it may be prudent to carry them anyway. Some people in law
enforcement follow the letter of the law. I recall riding in a front wheel
drive car in the 70s and getting hassled for having chains on the front
wheels... Took a bit of effort to convince the trooper it wouldn't work any
other way.
