Snow Tire Comparison Tests - Published reports available online!!!
I myself basically focused on comparing in these reports the Dunlop SP Winter M2, the Pirelli 210 SnowSport, the Michelin Pilot Alpin, and the Blizzak LM-22 (the top 4 northamerica-available contenders in my opinion) in size 205/55-16 H. The tests proved very insightful - but keep in mind that both FWD and RWD cars were used in the tests, that both 195/205 H-rated tires as well as smaller 175/185/195 T/Q-rated tires were tested, and that some tire brands changed models (while the same Dunlop was used in all tests, and for the most part the same Pilot Alpin, the Pirelli changed from the Asymetric to the SnowSport, and the Blizzak was never tested as it is new - the LM-18 was tested (relation to LM-22??) as was the WT-12 and the MZ-01/2).
After pouring over the test reports for 4-5 hours, I have found some very consistent findings, and I think I have come to a conclusion as to my best choice for a snow tire for the A4. I would be very interested to hear what other readers conclude from these reports. I will keep my choice to myself for now so as not to bias others (besides, I am no expert!).

Actually, the most consistently and most highly recommended snow tire was the Continental TS790!!, which, unfortunately, is not available in USA or CANADA (are you listening Continental - their technical customer service rep even denies that it exists - that's scary!). As for the Goodyear Ultra Grip - overall about midway up the pack of 12 or so - not a contender.
As for MY choice .... see other posting!
The winners were: Continental TS790 & Blizzak LM-18, with the Conti having a dry/wet performance edge and the Blizzak a snow/ice edge. Unfortunately, neither are available here, AND the Blizzak LM-18 LOOKS nothing like the LM-22, so I do not think any inferences can be made (as a note, Bridgestone US tech reps are unaware that the LM-18 exists)!!!
So, where do we go from here??? I had to focus on the tires available in NA

In a nut shell, I based my "meta-analysis" on pure performance numbers, disregarding wear, noise, and economy (rolling reistance). The idea was, choose the best performer as long as the non-performance characteristics of the winner were not way out of line (which they wern't). In the performance category, I crunched the data with a weighting of 40% wet, 30% dry, 20% snow, 10% ice performance. This distribution is roughly what I see on the roads here in a suburban location in Canada (near Ottawa, Ontario). While we get tons of snow, they are ultra-efficient at getting rid of it or melting it with salt, so we really only drive on snow at the height of a storm, with packed snow on residential streets and dry or wet (salted) freeways the rest of the time. I also focused primarily on those tests that used a FWD Audi or VW, and less on those that used the RWD 3-series BMW (I disregarded the Ford Focus study!), and only considered the H-rated comparisons.
The bottom line:
1 = Dunlop SP Winter Sport M2
2 = Pirelli 210 SnowSport
3 = Michelin Pilot Alpin
Based on the data, I clearly believe that the Dunlop offers the best all around combination of wet/dry vs snow/ice performance. The Pirelli seems to give better dry road performance at the expense of snow/ice, while the Michelin is the opposite with better behaviour on snow/ice but a softer less responsive dry/wet character.
Where does the new Blizzak LM-22 fit in?? It has pretty good snow/ice pedigree, but predecessors have been a bit mushy on the freeway. Apparently they have bettered the dry road character in this model, so it is probably an Alpin-type tire, but better. If this is true, then the order would be:
All-around (wet:dry:snow:ice 40:30:20:10 = Suburban?):
1. Dunlop 2. Pirelli 3. Blizzak 4. Michelin
Snow performance oriented (ie. Rural)
1. Blizzak 2. Michelin 3. Dunlop 4. Pirelli
Wet/Dry performance oriented (ie. Urban):
1. Pirelli 2. Dunlop 3. Blizzak 4. Michelin
A recent conversation with Eddy at TireRack pretty much supported this conclusion, but it certainly isn't gospel!!! Remeber, it is only based on my interpretation of the data, and I interpreted the numbers along the lines of the type of driving I most frequently encounter during the winter and the snow tire characteristics I consider most important!
Comments always welcome!!!

I also have a set of the previous Blizzak model in the same size (205/55x16) that my wife has used since 1997 on her GSX. I am not sure of the exact model designation. They are lightly worn despite the age because my wifes driving is limited to about 10 miles per day on relatively slow speed roads. We usually have the winter tires mounted from Dec 1 to April 1.
Neither tire is on the road right now and probably wont be until November'ish. You can make your own guesses on the effects of the changes I can see. Visual observations:
LM-22 is a directional tread design.
LM-22 feels like it uses a harder rubber compound but only slightly.
Blocks are a little larger on the LM-22. Spacing between blocks similar.
The cuts in each tire block (sort of like the slices in a Sperry Topsider) are similar.
I bought the LM-22 largely based on the excellent performance of the previous model on her GSX and the claimed improvements in high speed dry road performance. I commute about 70 miles a day...<p>2001 A4 1.8TQMS

Bringing Audi to Life for Audi Fans
Nice homework, however, but for tire comparisions of tires available here, that is why we take time to do our own driving & in house testingon the tires every year, so I get a chance to drive them all side by side to see first hand what the differences are (sometimes very subtle, sometimes not)
As always call me to discuss further- 800.428.8355, ext 369
Thanks!
