winter tire size for 21" rims

Typically I'd go with the smaller size and narrow tires for winter setup... I am taking delivery of a 2023 GLS450 in 3 days and it has 21" all-season tires. Based on my brief research and past experiences I am considering MICHELIN PILOT ALPIN 5 SUV in size 255/50/R21 all around. My prior 2021 GLS had 275/50/R20 hakka 3 SUV which was fine but new hakka 5 SUV in 285/45/R21 OEM size is crazy expensive $620/each.

Should I choose the Michelin Pilot Alpine 5 SUV ("MPAS") in narrow 255/50/R21 size or get VREDESTEIN WINTRAC PRO ("VWP") in the correct size 285/45/R21?

EDIT: Hakka 5 SUV is available at a lower price once I register as a member on the site ;-) $440/each puts them on the map while MPAS and VWP are $320-$330/each.

Pirelli Scorpion Winter did poorly in tests vs. the other 2 tires.

For summers I have a set of nice 23" wheels with summer performance tires.

I was told 21" and larger wheels automatically gets you a staggered setup (I have 21").

You should be looking for:

275/45R21 in front
315/40R21 in back

If you get this car, your days of buying the same spec tires are over! Ask you dealer if you don't believe me.
I've also attached the MY23 GLS450 Order Guide for your reference.

Sounds like I should hope that the strike/supply chain issues delay my new car until after the winter...
Is there no scenario under which it is doable to have 4 identical winter tires on a car that comes with a staggered setup (23", maybe, in my case)? I last had staggered tires on a Smart Fortwo a long time ago and I remember the skinny fronts costing 50% more than the larger rear ones.

I have 20" winters on the GL at the moment that are priced reasonably. Ideally, I'd like to keep that kind of size...

Yes, I haven't thought this through properly before ordering...

there are oem 20" rims for x167 but they are not as nice as 21" twin star with black accents.

new 2024 gls cars do not come with 20" wheels but I do think it's perfectly fine to put 20" wheels on them.

By definition, a staggered setup means the front are different spec from the back.

Using the 23" wheels as an example:
285/40R23 in front
325/35R23 in back

The first number is the tire width so the fronts are smaller than the back tires by 40 mm (about 1.5"). The second number is the aspect ratio, which is a % of the width to determine tire profile off the rim.

You can certainly go back to 20" wheels/tires but you will already have paid for the 21" since it's baked into the MY24 MSRP.

In the case of the 23s, I have yet to see winter tires for those, so a second set of wheels will be needed regardless. The question is whether I can put matching 20" wheels with winter tires on the car or whether I need to keep some staggered setup for that, too?

Dumb question, I know, but I am not quite there yet...

We know from MY23 cars that 20" wheels should be fine. The only thing I'm not sure about is if you buy a MY24 GLS and try to retrofit 20" wheels, will you be violating the warranty agreement and/or any wheel/tire protection?

There are no 20" wheels in the MY24 Order Guide so only the dealer can tell you the implications of going to 20" from a warranty point of view.

The warranty part is interesting.

I've been foreseeing this issue for some time and asked my dealer to price up a set of OEM winter wheels that I might buy at the same time as the car, but the salesperson I am working with is not so good with following through on promises... The good salespeople keep getting promoted, which is annoying...

I have had friends who have been down the road of different tire and wheel sizes than offered from the factory. Since they would be winter only, I would just swap back to the OEM wheels before taking it in for service. Realistically if the over diameter is the same (or very close) and the wheel/tire doesn't contact anything, MB wouldn't have a leg to stand on proving your alternate setup caused any failure.

When going with narrower tires on the same stock rims, ensure the rim width is within the spec for that particular tire size.

GL350 Bluetec and GLS580
I have the VREDESTEIN in the stock 21" format for my winter wheel setup

. I just took my first snow drive. I think my hakka 3's on my GL350 drives better in the deep snow; but it could be the tire width that is making the difference.
