GLC300 Spare Tire Options
 

We own a 2017 GLC300. My wife periodically makes long trips cross country to visit family. Distance between viable cities which might have a run-flat tire should she have a flat are well outside the 50 mile limit on the run-flat Perelli tires that come with the vehicle. After our first flat tire at 13,800 miles, we were told that all of the tires on the vehicle needed to be replaced. My wife is a conservative driver so we were very surprised. We talked to our Mercedes dealer and they said that 15 - 17K miles is typical for what you should expect to get out of the Perelli Run-flat tires. I was amazed and am not willing to replace tires every 15K. I set out to purchase regular non-runflat tires, a spare tire and spare tire changing kit. I was shocked to learn that in the USA you cannot purchase a spare tire or spare tire changing kit for the GLC300 (you can purchase these items in Europe). After days of research, I discovered that the spare tire and spare tire changing kit for the 2013 / 2014 GLK 350 fit the 2017 GLC 300. I ended up purchasing high end non-runflat Yokohama tires from Discount tire and I purchased the spare tire and changing kit off of eBay. Everything worked quite well and here are the details:

Very nice. Our 2017 "18 runflats are toast at 15K miles. No good replacement options but to keep buying the same crappy tire. I think I'm going to go this route as well.

How did you verify the proper spare to purchase? Just curious, the 18" version is probably the same but I'd need to research and verify that.

From what you can tell is there anything special about the inflator kit? We already have a nice one and I'd prefer to just buy a jack and lug wrench.

Thanks for posting this!

Sabre: I wasn't originally going to get a spare when I replaced the run-flats with Michelins because I haven't had a flat in over 20 years and various Michelin warranties say they'll tow the car to a dealer if it does happens, but inspired by your post I thought it cheap enough back up insurance to follow your lead. Found mine on eBay for $124.50 including shipping. Got it today and pleasantly surprised to find the salvage yard also sent the the compressor. Quite pleased and I thank you.

I put it in the back exactly as shown in your photos but I do have a question: Do you have a way of securing it, other than placing one edge under the flange at the top? I'd like to find an easy way to bolt it down rather than relying on gravity to hold it in place. Thanks

Hi ChinaBob
I was just wondering if the spare tire kit and the jack kit fits in the under compartment in the trunk for the GLC300 in the USA?
Thank you

The spare fits just fine, as well as the inflator with it. I did not get a jack so I can't comment about it.

thank you for this post! any idea if this would work for a 2018 glc300?

GLC300 2018 spare tire kit
 

anyone know of any spare tire kit that would fit a 2018 GLC300 18" wheels. my runflats crapped out at 14K miles :-(
thanks

I have 19" wheels, anyone know what specs spare tire would work? are there any older MB spares I could use? we have a local junkyard and I may be able to find one. thanks!

Mine is a 2019 and I got a tire on Ebay and a jack kit with air compressor also found on ebay. Total cost for these was tire with bolts $130 and jack kit was $90. I used the "best-offer" feature on both items and got them below the asking prices.

GLC300 2018 spare tire kit
 

thank you so much for taking the time to send this. your rear well looks ways bigger than mine! i have a 2018 GLC300, i looked in there & there isnt much in there but no way would a spare anything fit. guess im screwed. :-(

Believe me I thought the exact same thing when I first saw the spare tire, that there was no way possible it would fit in but after a firm downward push it did. The fiber material that is used here is very soft and pliable, I was going to cut a section of it out but gave it a good shove and the fiber trunk liner gave way and let the tire sink in. That fiber material trunk liner is sort of like an egg-carton and has some upward shapes and forms that are totally hollow and compressed easily going flat enough to let the tire seat itself in.

The spare tire kit I ordered off ebay from a salvage yard arrived today and after some alteration to the styrofoam holder with a saw I was able to get it into a spot in the trunk.

Doesn't the GLC 300 in Canada come with a spare?

2016 GLC 300 4MATIC Spare tire OEM
 

Hi ,
I have 2 run time flats in last 4 months and another one flat now . Trying to go to non run flat by putting a spare tire .My SUV GLC 300 tire spec is 235/60R18 . How do i get spare matching with the vehicle tire spec.? What do I search in ebay ?
Any help is appreciated . Thanks you in anticipation.

It appears that some people are using the 195/75R18 compact spare for the 235/60R18 tire. The difference in overall diameter is 0.4” — the 195 being slightly larger. I don’t know at what point the size difference becomes critical for sustained driving on the larger spare.

One thing i have been debating - the Bridgestone DriveGuard is a repairable RFT that has a 60k mileage warranty, only problem is that it is only 235/55 instead of 235/60 so it is a smidge shorter. Feedback seems to be that it is a great ride, comparable to non-RFT.

Spare option for GLC300
 

I found a new unused donut spare for a 2010 ML350 for the 18 inch wheels. Fits fine under the rear floor. Clears on all 4 wheel locations.

Can you take a picture how it fits ? Really like an idea of spare tire but fuse box makes me think it might not fix with floor lid closed.
Thank you in advance.

thank you . Not sure how easy it fits on GLC-300 trunk . Interesting to know if it fits underneath the mat. Also it costs approximately $ 300 including shipping . If you have any clues to get it cheaper please let me know.

Thanks for the pics and info guys.. purchased a 2nd hand kit on eBay.. just hope the 18 inch space saver works ok as I have 21's on my car =/

Sabre, Rick,

I also have 2017 18" runflats. The info above is for 19" spare. Will these fit my car?. Do you know what spare and rim should I use to go with the 18" (235 60 R18) tyres?

Thanks in advance,

Tushar.

Has anyone commented yet that an OEM compact spare is available on the MB USA build tool for 2020 GLC. Dealer should have the part number.
https://cimg3.ibsrv.net/gimg/www.mbw...99f02383b0.jpg

MY Dealer has no such option...... is there a MB part number associated for this $200 tire?

Yep, I contacted two dealers and neither one was able to provide any info on this tire. One of them offered a an alternative which cost $1,600 (complete with jack, etc. and tax).

I ended up buying a spare from 2015 ML350 unused with jack etc., for $320 on Ebay. This information was listed on another thread regarding spare tire. The spare fits nicely in the storage under the trunk floor, you can also lock the trunk floor.

I copied the below information from another thread so you can refer to the part numbers, you can do the same as the one who posted this info by ordering new instead of buying used from ML model. They are pretty much added up to the spare tire and kit that I bought from Ebay except that they are new.here are the part numbers I bought for my 2019 GLC4matic base/not Sport

Spare wheel 18x4 $314 online oem part # 164-400-00-02
Tire T155/90D18 Tirerack $129.41
Tire valve $5 oem part # 000-400-29-12-64
Wheel Bolts (M14x1.5x26mm) – I bought eEuroparts.com sku 18913. I think oem part# is 0009908307
Tools, including jack, for changing Spare tire, $81.90 oem part # 166-580-69-0

Good luck.

Where did SteadyRover get his spare? any info to pass on?
