2008 ML 63 Snowtires needed? Recommendations?
My long awaited Obsidian Black ML 63 is due to arrive on 8/20.
I will have a few months before snowflakes fall here in Madison, WI to enjoy the "summer rubber" on the truck...based upon you lucky 2007 owners' experiences, will I need to switch over to dedicated snowtires and if so, what brand do you recommend to get me through the winter? We do get the occasional snow dump of 4-6" here and I do need to get to the Hospital for work, so when it snows, I still gotta go! 
Thanks for all your help.

I am in the same boat. I have been thinking about getting a set of snow tires as well. I was looking at some Scorpion Ice & Snow to put on the stock rims. I had a GC SRT-8 last winter and I put a set of 255-45-20 Scorpion Ice and Snow on the stock rims. It did work but I was not a fan at all of the 4wheel system in the Jeep. It was very rough when the traction control kicked in. It felt like it was being pulled at all 4 corners. So I am hoping the ML will be much better. My only concern is that the tires will be too wide as this is not a good thing for traction in the snow. One thing I may do is get a second set of rims and then put some snow tires on them. When I took my Jeep to Goodyear I learned that they charge more to mount run flats, a whooping $100 per tire.

Hopefully we can get some info from other members that have had their ML in the snow/winter.
Turned out to be excellent throughout the New England winter last year...
" recently mounted a set of 275/40/20 Pirelli Scorpion Ice & Snow on the stock rims. Beforehand, I debated going with an all-season tire to keep as much sport / performance as possible. But I then did a mental reality check of how tough winters can be in the Northeast, so I decided on this true winter tire (at least, as true a winter tire that 275/40/20 can be...).
The car has not yet had an opportunity to be driven in snow. The car has gone about 200 miles so far with the winter tires on, primarily just normal day-to-day driving. Steering response and feel is not quite as sharp as with the stock tires, as is to be expected. Feels like about 10% of the response / sharpness is gone, so it still feels quite good. Road noise seems the same."
I think I will be ordering these from the Tirerack.com pretty quick as they only make a limited number.
I have dedicated snow tires for my 2007 ML63, and the vehicle handles nicely in winter. I don't know the brand (I think either Dunlop or Continental) since they are in storage. I would not drive it with summer tires in the winter, because stopping and steering ability can be considerably reduced. Even with AWD, traction can be a problem with summers. It's my understanding that summer rubber compounds do not perform well in the cold.
I would ask the guys at Zimbrick for their recommendation. That's what I did, and I'm very pleased with the results. The handling of my winter tires is not that far off from the summers.
Good luck, and I know you will enjoy your ML63. I have 16,000 miles on mine, and have had no problems. The engine is magnificent and the quality level is miles ahead of the previous generation ML55.
Tomorrow is the big day for the ML63 pickup...can't wait

I will see what the dealer recommends for my 500HP snowplow with 20" wheels...I should be safe until November with the summer "racing" rubber, then I will have to swap 'em out for sure.
Here's some pics from yesterday at the dealership.
Have a great week!

Regarding snow tires, I would not wait to order them until you need them. I recommend you get them now and store them. They can be hard to find nearer winter.
My snows are 20" and I have them put on the same wheel set as the summers. They are an identical size to the summers. I don't follow the common wisdom of putting on narrower snow tires to give better grip. I've never noticed much of a difference in the snow when I did, and the dry handling suffers with narrower tires.

so that it's a must be in germany in winter.

We LOVE the ML 63..

If any of you are "lurking" out there wondering on whether to get one, it's a no-brainer...most awesome SUV out there currently! Order yours now!

It was built July 24th... I "strongly urged"
the dealer to expedite delivery and got it on August 13th...what makes it even more fun is that my brother checked out my ML 63, noticed they also had received a silver 63 and is now the proud owner of that ML!
The salesman could not believe his good fortune to have hooked up with 2 fanatics!

Dr. No, does your 2008 have the rear door switch?
Here's a picture from the 2007 online manual...
It looks like there's a little rectangular hole where that switch is supposed to be, but it's empty.
20" winter wheels with 295/40/Zr20 Scorpion Ice and Snow.
They want $4400 for the set up.
I think I will just buy the rubber and stick it on the stock rims.
I just readed my ML63 in and i have pirelli snow tires that i had put on last year, i was going to put them on ebay, but if you would be interested please let me know, the snow tires have about 6500 miles on them.
305/45 will have a much greater OD than stock. Your ML will have large spedo error and possible be very slow off the line. You could get away with 305/40 I think but still will have above errors. If you lower it they will likely rub as well. I kept the stock rims for winter and have a set of Scorpion Ice and snow in the 295/40 R20 on order.

A 305/45 will have a circumference of 96.8 inches vs 92.0 inches for stock resulting in a spedo error of 5.2% low. A 305/35 would be like lowering the gear ratio and result in a 3.0% high reading on the spedo. (60mph indicated would really be 58.2 mph)
Actually a 305/40 is only off by 1.1% Acceleration would be different but how much in the real world would be interesting to see.
Thanks for the calculations. Does anyone know if Bridge stone makes any blizzaks close to the Scorpion Ice & Snow size of 295's?
I have a set of 255/45/20's Scorpion Ice & Snow in the garage but I was not too fond of them when I had them on the GC SRT-8

Very handy site on my fav list.
I've been told its only Dunlop or Pirelli from my local dealers (in 20's). I shold have them on by mid October so I can let you know. Had the Scorps on a QX4 in 03 or so and they were decent. (preferred the Blizzak)

Obviously, these are not snow tires, and I didn't go this route for winter performance. My primary motivations were (1) to get away from the stock Continentals, (2) to get a bit more rubber between my wheels and the road (I actually go off-road a bit), and (3) appearance, plain and simple. The vehicle drives a bit less like a sports car and a bit more like a locomotive now, but that's fine with me. I have a C55 as my second car, and that one will get me my "boy-racer" kicks.
I also understand that the speedo will have a marginal error, but that doesn't concern me in the least. Most speedos have a 2-4% error right from the factory, so that's no big deal. My dealership and I did a lot of research before making this move, and I'm confident that I will not have any problems. I'll report back if there are issues or problems.
