GLK winter tires
Regarding downsizing wheel, if the bolt pattern and offset meet spec for your car, you should be able to downsize by using a higher profile tire to keep speedometer etc correct. I am quite sure the off road version GLK I saw in Spain was fitted with 17" wheels.
You are right, it is impossible to find any winters in 19 or 20" to fit the GLK.

I'm thinking of going one set and pick up my favorite all seasons winter, Nokian WRG2. Maybe I'll do the following:
225/70R16
or
225/65R17
I just worry it'll be difficult sourcing the 17 inch for such a new vehicle.
Bridgestone Blizak WS-60 @ $113 each and Pirelli Scorpion Ice & Snow @ $128 each.
Also, FYI, MB has an attractive 5 spoke design 17" alloy wheel for the GLK.
I would suggest that you choose a MB approved tire diameter and size, otherwise your speedo reading will not be accurate and perhaps the vehicle's handling could be adversely affected as well.

The problem though, is that while we can find 235/60 R17 for the front, if we were to stick with MB specification (giving the car wider 255 tires like all its packages in 17, 19, and 20 inches in the back), there is no winter tire for the rear in 255/55 R17 even from TireRack.
I guess this means we may have to fit the narrower 235 in the rear instead of the 255, not sure how it will affect handling, as the car's torque is split 45/55 front/rear.
By the way, do yo have any pictures of the 5 spoke 17" alloy? My dealer doesn't seem to know how to order one.

My guess is the 235s will do the job in the deep snow where you would want narrower tires rather than wide, floaty ones on the rear. No doubt the GLK owner's manual will have some reference to recommended snow tire sizes.
You can find some pics of the 17" 5 spoke wheels on the MB configurator site @ www.mercedes-benz.de/content/germany
Click on Home Page, then "Konfigurator", then GLK, then choose the various options. By the way, it's all in German !

Looks like it'll be 235/60 R17 then!

Please note that this is the version of the manual intended for the German market. Could our fellow board members pull out the US and Canadian edition and let us know what they say. Or are they silent in this area?

In another thread "Iventory Leader...." MBWestminster said std MB line is no chains, but people use them at own discretion all the time. Also said Pirelli will be providing 20" Scorpian snow tires, like those for GL and ML65, but no delivery date.

As far as Pirelli Scorpion snow tires for the GLK, these tires are available in 235/60 x17" size from Tirerack to fit the 17"x 7.5" 5-spoke OEM alloys available from any Canadian MB dealer.

Obviously, it will be less expensive than a separate set of snow tires on 17" alloys, but surely the 20" wheels with very low profile snow tires are not a set-up to be recommended for winter handling and performance, assuming such tires even become available.
Just curious, re: the 17" alloy wheels and winter tires -- did your local MB dealers have the option available for you to order these, or did you have to kind of go in and spell it all out for them since it doesn't appear to be a factory option?
It looks like I'm going to have to special order the GLK I want anyway (none of the color combinations or common package options that are currently out in the first batch of vehicles in the US match what I want), so I am hoping that I can just ask them to build it with a set of 17" wheels from the get-go instead of the ridiculous 19s or 20s. Just don't know if that's even going to be an option or if I'm going to have to order it with the standard 19s and get the 17s after the fact....

From previous posts, it appears that the US dealers do not have the 17" OEM alloys in their parts listings, let alone have them in stock. As far as Canadian GLK orders from the factory are concerned, there are only two options, 19" or 20" wheels. Here's a suggestion : if you want to purchase the 17" wheels, suggest you contact the nearest Canadian dealer to you (www.mercedes-benz.ca) and take advantage of buying in US dollars that are worth approx. 27% more than a CD$.
Smaller gas engine, snow tires, 7 speed 4-matic.
So, there's ...
price of tires = ??
price of wheels = ??
price of sensors = $500.
The system installed in Canadian vehicles thus does not measure individual tire pressure, as in the US vehicles, but relies upon the fact that a deflating tire will rotate at a different speed than a normally inflated tire, thus triggering the speed sensor that is attached to each wheel's brake caliper.
This system is obviously less expensive than the US one, but it nonetheless warns the driver of any significant loss in a tire's pressure. What it won't do is indicate which tire has lost pressure; that requires the driver to stop and perform a visual examination. I know this from first hand experience during the past summer, while driving to Moab, Utah !

Heavy snow alternating with freezing rain and double digit subzero temps.
Have rarely seen bare pavement since I got it.
20" all seasons behaving well, good traction in snow, climb icy hills no problem.
