may I know if you guys replaced the original tires (and what brand have you guys bought) or did you just rotate the original ones?
 
Hey B, I replaced my OEM Michelin run flats with Michelin non-run flat snow tires and am not taking them off. The ride is soooo much smoother with non run flats and I put 5,553 miles on in 17 months so not worried about excessive wear. I drive in an urban environment so other than a nail every year, not worried about flat tires.
 
I use Nokian Hakkapeliitta R2 tires (Run-Flat) on another set of Mercedes OEM wheels in the winter. Winter traction is awesome. I am a believer in Run-Flat -- never needing to stop on the insane highways, bridges, and tunnels of NYC is very important to me. And Nokian Winter tires are all LRR (Low Rolling Resistance)

Tire size is 225/50 R17 (VERY COMMON SIZE)

Nokian is my favorite brand -- even in Summer/All season Compound : Here are those choices:

http://www.tiresbyweb.com/tbw_tiresearchadv2.aspx?treadwidth=225&profile=50&rimsize=17&Winter=0&Pageindex=1&selectedManufacturer=Nokian%20Tires

Nokian Hakkapeliitta 8 - Studded Tires
$264 each ultimate STUDDED winter traction, RUN-Flat

NOKIAN HAKKAPELIITTA R2 TIRES
Winter Studdless Tires $246 each ultimate studless winter traction, RUN-Flat (This is what I have an I use the OEM Michelins in the Summer)

NOKIAN ENTYRE 2.0 TIRES
Premium All-Season Tires $111 each, Built Like Steel, 720 AA rating, NOT Run Flat. For that price buy an extra one!

NOKIAN zLINE TIRES
Ultra High Performance Tires $174 each, probably what I would get for Summer only, RUN-FLAT

NOKIAN WR A3 TIRES
All-Weather Passenger Car Tires $252 each, RUN-FLAT, an interesting compromise if you don't like changing summer/winter rubber and you live somewhere where you get snow/ice. Dedicated winter / summer rubber is better.

TIRE-RACK has 5 choices - ALL PIRELLI - for the Summer or All-Season run-flat in the OEM size: (Low Rolling Resistance Only) on Tire-Rack.

I like Pirellis -- and they are price competitive with the Michelin OEMs. (If you buy the ones for BMW - not Mercedes (Same tire) They say BMW OEM Star on the sidewall.

The OEM Michelin PRIMACY MXM4 ZP are not Low Rolling Resistance!!!!

Two choices, All-season or Summer Only

One more choice: (AVAILABLE AT THE END OF SUMMER 2016) Nokia's newest "All Season" tire:
Tyre manufacturer Nokian has just presented its new WR A4, a winter tyre designed for high performance cars. Promising and with a strong focus on technology, we were given the chance to test it at Nokian’s stronghold in Finland.

Finnish tyre manufacturer Nokian is the undisputed specialist of tyres designed to deal with winter conditions. Its test base located at a stone’s throw from the Arctic Circle, and where we discovered the WR4, is a good example of the resources this manufacturer has invested to develop its products. Indeed, of all the winter development centres we have had the opportunity to visit; this one is the most impressive. The facilities available for engineers allow them to work in the best possible conditions. The 0,5 mile (800m) long ice tunnel used for braking tests is a good example of the resources invested and the optimal conditions used to develop the WR A4.

Significant performance improvements

The WR A4 will replace the WR A3. It has the role of being the sportiest tyre in the Finnish tyre manufacturer’s winter range, just like its asymmetric tread pattern suggests. A design shared with the tyre it replaces, even if the improvements announced are significant.
Indeed, Nokian has stepped slightly out of its role as a snow specialist to present this tyre as being ultra-versatile. A step forward, even though this manufacturer likes to remind us that tough winters remains its speciality.
As such, this tyre is clearly geared towards wet grip performance with a tread designed to efficiently remove water. From its tread design to the polished grooves, every effort has been made to ensure this tyre delivers performance in pouring rain.

Obviously, this has not been achieved at the expense of pure winter performance. This tyre benefits from all of Nokian’s expertise, especially in the development of a latest generation tread compound.
The sporty and dynamic dimension is ensured by a reinforced structure using the same technology as for bulletproof vests.
Testing on Finland’s roads

The WR A4 will be available at the end of summer 2016 in more than 50 sizes ranging from 16 to 21 inches for high performance and/or sports vehicles. Several Run-Flat sizes will also be available.
 
Receiving our first big snow job today, expecting up to 12 inches in NYC. Tomorrow, will take it out for a spin (hopefully not) and see how it fares with my gently used Michelin snow tires. As wtzouris suggests, will remember to go easy at starts to minimize wheel spins and regen brake to slow down rather than stomping on brake. I do both to economize so just have to remember to do so in the sloppy streets to/from work.

Safe driving everyone in the NE.
 
With my Nokian Hakkapeliitta R2 tires I find that the traction control is a little too aggressive, so I have the menu traction control on/off menu at the ready on the steering wheel and drive with the ability to turn it on off on demand with the OK button. Especially for climbing hills in deep snow the car does better with some slip allowed (traction off) it allows the tires to climb the hill better. Once I am driving on a flat or downhill, I turn traction back on.
