I've just realised that I've got a bit confused about the ML & GLC sizings. The GLC tyre is 155/80 R19 whereas the ML is 155/90 R18. I.e. 18 vs 19 with different profiles to give much the same overall daimeter. The ML emergency tyre is actually slightly close to the standard GLC tyre diameter than is the GLC emergency.
However it's the wheel size which is the tricky part. As tgcbr pointed out, the GLC wheel is 4,5 B x 19 H2 ET 35 whereas those pix show that the ML is 4.00B 18h2 ET40 I take it that that's a 4.00B and not 4.008. This means that ordering an ML spare long distance other than the 2010 is going to be a bit of a gamble.
But a quick search indicates that other German marques may use the same emergency spare. Hmmmmmm
I didn't even have that information when I was looking for a spare. I took a gamble and ordered this one based on the overall diameter. Fits and rotates on both front and back , however I have not driven any significant distance on it. If I ever had to use it I would mount it on the front.
If I ever had to use it I would mount it on the front.
Why?
I've just switched to non-runflats, and my interest in one of these is as an around-town spare, to get me home and to a tyre shop. (I travel distance with a fifth wheel, but would rather not lug it around town.) I've bought a tyre plug kit, but in town it may not always be convenient to stop and plug. I'd like to give myself the best chance of getting a nail hole plugged properly (happened once already) and so would rather not use a slime kit. It's not clear whether a tyre repaired with a latex-based tirefit kit could still be plugged (I asked a local tyre shop and they were reluctant to say even "maybe"). So an affordable emergency may make the most sense.
At the risk of appearing obsessed with emergency tyres, here are the specs from the MB manuals that I could find:
2008 ( I assume same as 2010, as I think both are W164)
Model ML 320 CDI, ML 350, ML 550
Rim 4.0B x 18 H2
Wheel offset 1.58 in (40 mm)
Minispare tire: T 155/90 D18 113M or T 155/90 R18 113M
2004 W163
Model ML 350, ML 500
Rim 4 Jx18 H2 ET0
Wheel offset 0 in (0 mm)
Space-saver tire T155/90 D18 113M1
It's easier to find the earlier W163 spare, and the tyre diameter is the same, but the vastly different offset concerns me. Since the 2010 is known to work, thanks to SN's gamble, that's the one to look for.
May have found one. SerenityNow, in that third photo in the latest set - the one showing a wheel size stamp - there's a number on the right that I can't quite read. I think it has a Mercedes star and a number. Is that right and is the number A1644000002 ?

Hi Bips,
I am very interested in what you find as I am keen to get rid of the run flats when their time has come an get a space saver spare.
Did the new tyres improve your ride?
You might want to be careful with the W164 runflat and your AMG front brakes. To me these brakes look bigger than standard but I haven't been able to find any specifications.

Interesting point. It's certainly true that the front brakes are a fair bit larger than the rear, but I assumed that this was normal. The specifications for the AMG Line pack in the brochure as it was when I bought mine don't mention the brakes:
• 20" AMG multi-spoke alloy wheels (688)
• AMG bodystyling comprising front & rear apron (P31,772)
• Sports suspension (486)
• Privacy glass dark tinted from B-pillar to rear (840)
• Sports steering wheel with flattened bottom section & gear shift levers
• AMG sports pedals in brushed stainless steel with black rubber studs
• AMG floor mats (U26)
• Nozzle surrounds in silver chrome (P29)
I guess I had better make a trip to the dealer and check against a regular GLC.

Of course the fronts are larger than the rear. What I am referring to is that on the AMG line the front brakes and rotors look like they are larger (as well as being cross drilled) than a regular GLC.

Might be a trompe l'oeil caused by the multi-spoke wheels. I'll check. Thx.

Yes, it is a Mercedes star, and I will have to go back and look at the wheel to confirm the first three numbers after the A
OK so I took the wheel out and even take it out in the sunlight but it's very difficult to read that stamping. It is either as you put it above A1644000002 or possibly A644000002.
As far as the spare wheels from the W164 versus W163; The 40 mm offset on the 164 is closer matched to the 35 mm offset recommended for the GLC minispare. However the 0 mm offset shouldn't pose any problems with regards to fitting, it essentially pushes the rim "outwards". It would be nice if someone could find a W163 spare room and just borrow it to see how it fits. I guess the best option would be a friend or maybe even a dealership that has a used W163 on the lot.

Reason: Grammar
Thanks for going to that trouble. Much appreciated. The advantage of the W163 is that it's easier to find. The advantage of the W164 is that the tyre on it is going to be newer. I agree that a zero offset should be safe, but the closer match of the W164 is less of a gamble, and particularly that you've verified that it fits. I just need to verify that the AMG Line pack on my GLC hasn't given it larger brakes.
Of course the fronts are larger than the rear. What I am referring to is that on the AMG line the front brakes and rotors look like they are larger (as well as being cross drilled) than a regular GLC.
I was at the dealer today, but there wasn't a regular GLC to examine. There was a GLC AMG 43, a GLC coupe, and a GLC with the AMG Line pack, pretty close to my own GLC. The AMG 43 brakes are clearly different, however the dealer said that the non-AMG 43 vehicles all have the same brakes, i.e. the AMG Line pack doesn't change the brakes. So the W164 spare that fits SN's GLC should fit mine. I took a few crude measurements and there's a reasonable chance that it would also fit the AMG 43, but there's no guarantee.

Hi Bips,
Looking at pictures online, the AMG line front brakes and non AMG line brakes look clearly different, both rotors and callipers. Wether they are different in size is a complete mystery as I can't find any specific info online yet. When looking at some spare parts it clearly states that the brake parts listed for a a GLC300 are not for GLC300 with AMG sports package.
I'm a little confused. Anthony's profile says Sydney Australia, but he's referring to a GLC300, which last I looked was not available here. It's a US designation, isn't it? Different countries have different standard specs and different options and options packages. I went to the MB USA site and I can see that the 'sports' package, which gives you AMG Body Styling on the 300, also gives you the 'Sports Brake System', which does look different to the standard brakes here. But I can't see from the Australian MB configurator that the brakes change when you add the Australian AMG Line Pack, and the dealer said they don't. TBH, without a non-AMG to compare we're arguing in the dark, but so far I haven't seen any evidence that they change on the Australian model, other than on the AMG 43.

Yes, I am from Sydney. I refer to the GLC300 only because that is where I am seeing the parts listings for brakes and the AMG sports package difference.
Just take a look at carsales.com.au for pics and you will see the difference in the brakes between a regular GLC and the GLC AMG line that we both have.
It is crazy that I can't find any specs on the difference but visually they are clearly not the same.
As you suggested, I had a look at Car Sales which is where I got the selection of images below. I have to agree that at the very least there appear to be cosmetic differences. The AMG-Line brakes have the brand name written on them, and are probably more scalloped. But it's not clear to me that they are larger. If anything I would have said the opposite.
Thanks for alerting me to this potential issue. It seems that I'm going to have to try to find an non-AMG-line specimen. Having just spend a couple of grand on new wheels and tyres, I don't feel inclined to take the same gamble that SN did, even though his experience makes it less of a gamble for me than it was for him. But in the end I may have to.
2016 GLC 250d AMG pack, 2017 GLC Coupe 250d AMG pack , 2002 BMW 330Ci convertible, 2021 BMX X1 sD20i
I receiver a quote from MB for a 'mini' spare $822.27 + 10%GST.
spec = 4.5 X 19h2 T 155/80r19 114m. not sure what 114m means ?
Not sure also when comparing to W163 or W164 ? Also impact of 18" or 19" when running 20" alloy rims.
Additionally GLC mini is Alloy, so use same wheel nuts/lugs. W163 type are steel, so need I guess to have steel lugs, shorter length at 38mm ?
Just more confusion, but I guess the collective minds of the "Borg" here will find it and come up with a workable solution.
Cheers
Just found a 2006 ML350 Spare for $50 (never used) and gave it a try. It clears the calipers and wheel well fine. All I need now is the correct size lug nuts. Went to Pep boyz and they said they did not have them. Anyone know what should I get?

The AMG brakes might look smaller because the wheels are bigger.
Looking at them though I would be surprised if there was much of a size difference and I would suspect the ML space saver would fit given the size of the ML brakes
It is indeed a 19 inch alloy wheel but be warned, it does not fit under the floor of the GLC.
The wheel is so big, that it fills most of the boot. I use it only when I tow a caravan (you call it a trailer in the US) and when I do so, I carry the wheel in the caravan.

Yes it does fit. I went to my dealer today, tried it and ordered it. You have to take out everything else, but it fits. In a week or so, i'll come back with pictures.
