Will the donut from a 2019 GLE 350 4Matic work on a GLC300 4Matic without any modifications? The part number is 1674000300 and the tire is T155/80R19. I currently have 18" wheels and assume I might need new lug nuts but other than that would be it be plug n play?

Juan Flores

what is the rim part number? Is it 1644000002? What about the tire size? 155/90 R18?

thanks!

I went with the Griot kit: https://www.griotsgarage.com/product...pair+system.do

Do most people who swap out the run flats with a traditional tire do so due to the ride quality (and abbreviated longevity) or for the eventual higher replacement cost? I see the OEM run flats are only $30 per tire more than a traditional tire. In some cases they are are as much or cheaper than a traditional tire.

In 2011 I had a BMW with run flats and replaced them with traditional tires and indeed the ride quality was better. Wanted to check if thats the same situation with you folks. Being as I have a leased GLC 300, just wondering if its worth the trouble as we'll barely have 20k on the car at the end of the lease (my wifes is the driver and this GLC will be a true cream puff). If I have to replace the run flats, then new run flats are not crazy expensive.

This looks like a nice little kit to have. I think I plan to keep my run flats on my GLC but may get one for my truck. Changing those far larger AT tires on the side of a road is not exactly easy. Thanks for sharing.

ajmtbm

Thanks, that looks like a nice kit and very reasonably priced

while i believe the ride would be better with non-RFT, i am not unhappy with the ride and am considering non-RFT mainly primarily because of the expected 30k or less miles available with the scorpions. the non repairability is also a concern. The Michelins i am looking at dont really appear to be much cheaper than new Scorpions, but in my opinion would even be worth paying more for given nicer ride and longer mileage

i have 20k on mine now and the wear is noticeable; i may not even reach 30k which sounds like similar to what others have seen. I have another vehicle with same size 235-60-18 Mastercrafts with 25k miles on them and they look brand- new

Just wanted to follow-up. Does anyone know if the donut from a 2019 GLE 350 4Matic will fit on a GLC300 4Matic without any modifications?

Thank you, this is very helpful. My friend just bought a 2019 GLE and wanted to replace the spare with a full-size tire so he gave me the donut. Before I purchase the parts you provided, I was hoping that I could use the donut I currently have without any issues.

TheGreatOne45

Any ideas? Is the 2534000300 wheel similar to the 1674000300 wheel?

ajmtbm

the 2020 comes with option for spare tire, i would assume this should fit in 2019, maybe better to wait for that?

Hello I’m a new owner of a GLC 300 4matic base.
Does your acquired spare tire kit fit in your cargo bay with the cover closed ?
Thnx
Pahunter.

fred9x

Yes, spare fits (tightly) with cover closed(handle clicks shut).

Jeff Graham

Super ! Now next question (sorry). Is there a Mercedes oem spare tire that conforms to fred9x individual parts purchase. Minus jack tools.
Thnx

Jeff Graham

So. You’re say a 18 inch ml350 doughnut style spare
will fit into the 2019 GLC 300 suv base model along with jack tool kit ? All while able to close cargo lid and latching. 🤔

labmaster02

This is the one I got off of eBay for $175.00 and a complete jack kit for $99.00. They fit my 2017 GLC300. It all fits under the hatch with a location for the jack parts and lug nuts.

Ok so cutting to the chase. Has anyone on here
successfully come up with a 18 inch DOUGHNUT style spare tire that fits into a 2019 US GLC 300 base suv With the deck board closing ? If so. Can you please provide your source and part number/s maybe pictures. Thanks.

2020GLC300

Is there anything different between the 2017 and 2019? Seems like the one they are posting above would work just fine.

I can't give you a part number, but I ordered a 2020 due for delivery next week and had the option of ordering an OEM compact spare tire with it, which I did. It was $200 USD. Don't know why it would not fit in your 2019. Having said that, it is possible it comes with a different liner in the underfloor storage area to accommodate the tire, while allowing the the deck to close flat.

2020GLC300

Well, I just order the one shown above for my 2020. It was $90 including shipping and taxes from eBay. There's a ton of them for sale. Looking at the area under the trunk floor, it looks like a 4" spare will fit. We will find out!

I also order shorter bolts for $24 and a complete jack with tools for $36. So $150 for everything. I will report back on whether it all fits and works. I'll definitely do a test tire change using just the items I bought and drive the car to make sure everything will work when it's needed.

Ok 👍 great I’ll be anxiously waiting for your feed back report. But the other gentleman may be right with the 2020 having a different cargo liner. Thanks for the updates. Much appreciated.

Hello Glc2020

Just following up. Did you receive your spare kit you ordered and does it fit in your cargo area below floor hatch ? Maybe a few pictures if you were successful.

Thanks
jeff

2020GLC300

Yep. Posted a new thread for 2020 models on here.

Long story short, it all works, I’m happy with it all, but spare only fits on the rear. So if you have a front flat, you put spare on rear first, then rear on front and front in trunk.

There is a bigger spare available but I don’t know if it fits under the floor like the one I got.
