Snow Tires with Quatrro

[Suffolk]

Re; Winter tires on a4 and other (what works best)
Hello:  My Winter tire input:

Back in the day when I bought my 4000Q I couldn't understand why the quattro
could do 360 spins on the Mass Pike.
It was because of the "shoes" on the car.  (And agressive driving beyond
what the conditions warranted.)
The tires were faux Goodyear Eagle GT's.
Like wearing loafers while climbing a snow covered ramp, the "shoes" (tires)
MAKE ALL THE DIFFERENCE!

I run Pirelli Winter 210P's (discontinued?) a little narrower than stock
wheel width, and change to a new set of four snows every second season.
The tread lugs and agressive high speed sidewalls (HR rated) with the sipes
in the tread block make the car run thru anything.
(except 12" snowplow drifts when the cars undercarriage hangs the tires off
the ground)
The quattro drive system will propell any "Audi" car with any tires thru the
snow and up grades like hills.
*** its the deep tread WINTER tires "shoes" that keep the car on the road
with control, and make the car track where you steer or brake it. ***

All seasons are all purpose which don't accell at either (summer/winter)
task at hand.
The agressive tread lugs work well (in my opinion during wheel lock-up (Non
ABS 86 4Q and 90 200 TQAvant with the ABS -off))
 in the RARE instance that the built up wedge or frozen sand, snow and slush
actually can shorten the cars
stopping distance in "off the road" or straight line braking.
ABS wins out the other 97% of the road conditions.
Some Audi literature mentions NOT to use snows though.  Which would you want
: Drive train wear or sheetmetal damage/being stranded?

Four snows for "shoes"! Boston to New Hampshire ski country I run circles
around normal cars, 4wd trucks, and SUV's until the snow depth reaches ~8"
unplowed.
