What size rim did you get? I traded my GLC for a GLE just to get a spare. My daughter still has her GLC. I had her put standard tires last time and have been trying to find a spare that would fit under the floor board and fit the car. I believe her rims are 17inch.

19" rim with a space saver tire. The tire is compressed, but expands to full size when inflated. Also need a compact compressor to inflate the tire

That's great to hear. I have just purchased non-run-flats for my 2016 GLC300, and want to purchase space saver spare tire. How did you specify the spare tire to make sure bolt pattern matches and there is no interference with brake disc? Will be great if you can post the complete specification for space saver spare tire that you purchased. Thanks..

I made a mistake , my rim size was 18". In the pictures below you can see the tire compressed, the inflator, and the bag containing the jack, lug nuts, and lug nut tire iron. Also you can see the tire size in one of the pictures.
I got the tire on e-bay, I made a low ball offer and it was accepted. I bought the jack , tire iron, and the lug nut rods from MB, the lug nut size is M14 1.5 23 mm . I inflated the tire and replaced the right front tire with the spare. I drove the car and there was no interference with rotors front or rear. Hope this helps Alloy wheel Tire Wheel Rim Auto part

New member here, wanted to chime in. I happen to stumble upon this forum after doing a Google search on the GLC300 Tire problem. The search did show a good amount of reported issues regarding this topic. I was expecting to see more on this forum besides the 4 posted above (unless I'm looking in the wrong place). Around 9,500 miles I started noticing a vibration that was noticeable in the brake pedal. As time went on, it became increasingly worse. Extremely noticeable in the steering wheel. I was driving home from vacation at the beach and I had a hard time controlling the car at highway speeds. I knew I had an appointment with my Mercedes dealer in two days for my 10K Service A. In 2 weeks it will be my 1 year anniversary with my GLC with 10,400 miles. While at my service appointment, I explained exactly what I was experiencing and told them the car is not safe to drive. After inspecting, they said the tires are shot and need to be replaced, they stated they were "Feathering". I had never heard that term before, but I have been reading a lot about it. My advisor told me the Pirelli Scorpion's are junk and they do not recommend using them as my replacement tire. They quoted me a price using Continentals or Michelin's. Well at 10K miles and under 1 year of ownership, I SHOULD NOT BE BUYING TIRES. I did not replace the tires yet, I wanted to do a little digging and research, PLUS, I don't have an extra $1400 on hand.
My 4th Mercedes, I really don't want it to be my last.

A couple of questions:

Is it true you have to put on or use MB approved tires?

Anytime I have bought a car (I've bought a lot too), there was always a tire warranty booklet in the packet of documents, there is none for the Pirelli's, should there have been or are they not warranted?

If Pirelli does not stand behind their product, does Mercedes stand behind theirs?

Any recommendations for replacement tires...

FYI, I did open up a ticket with MBUSA this afternoon, I actually did this because the vehicle is unsafe to use, so if something should happen, I wanted it on record.


One more question...

Do I have the option of NOT replacing Run Flat tires with standard tires? It's not leased, financed.
I have the same problem. 2020 GLC 300. I was told by Mercedes there isn't anything they can do. Shouldn't there be a warranty on these tires. To at least pay for some of the cost.
I also do not have any paper work on the tires with my paperwork.

I was told by the dealer you would need to replace the tire, not 100% sure
I just bought my 2019 GLC 300 SUV the other day. The tires brand that's on it is Continental Crosscontact LX Sport. This is the first time I ever had run flat tires. I understand the concept of how run flat tires work. The question I have is that if you have a nail in it, can the service shop service the tire like the do with normal tires where they remove the nail and patch up the hole? Or does the tire have to be replaced?
I had a nail on one of my tires. It was complex flat when I noticed it the following morning. I inflated it and took it into Costco tire center and they were able to patch it up.
My 2019 GLC300 is a little over 2 years old with over 11k miles on it. To be honest, I haven’t encounter the problems that I’ve read here. When I took it into Mercedes service center for annual maintenance, everything got a clean bill of health. I then take it a local European service center for a 4 wheel alignment. As part of their service, they checked everything again including tires and again, gave a clean bill of health.

My GLC needed new tire about 24k miles and I was shocked since my Lexus could take me 40-45k on a set of great tires. I was told Pirelli tires are made from a softer composite to give the car a smoother ride, which is aka - put the cheap tires on the Mercedes GLC and don't tell the customer.

Recommend Michelin Crossclimate SUV non runflat.
I got the Crossclimate SUV on my Mercedes GLK 220d 4matic. Drove 2 winters and 2 summers, thru snow, slush, wet, dry, scorching heat you name it. Outstanding performance in all conditions. And the biggest surprise was how comfortable they are. My wife noticed that immediately, said it felt like I did something to upgrade the suspension. They are also very quiet. In fact more quiet and comfortable than the Goodyear Efficient Grip I used as summer and Nokian WR3 SUV for winter.
Once the current Bridgestone Dueler runflat on my GLC 220d are dead I will replace them with the Crossclimate. Highly recommended

I changed all 4 of my 20" tires yesterday. I got 48,000Kms out of the original Pirelli run flats after 2.5 years.
However, I decided to go with regular tires. I hated the ride on the run flats and I have to say, my GLC now rides as I expected it to.
I don't have a spare, yes, I'm taking the risk, which is against my nature.
Went with Michelin Pilot Sport.
Hi there,
I am doing the same thing on my 2019 with 20” tires. Cannot wait to get the run flats off the thing.
I am curious if you set the air pressure the same as the recommended for the run flats, which in my case is 36 front and 42 rear.

I ended up putting Nokian tires on my GLC, since I moved from San Francisco, CA back to CT. A few dealers in town recommend this tire for the GLC. My Mom has these tires on her Mercedes 300 4-Matic and they have been excellent, ride well, very smooth ride. So far I only have 300 miles on the new Nokian tires, and they seem fantastic. Here is pic of the Pirelli tires I replaced. Downright scary. Good luck.

For me, not a fan of run flats but found under the lid for the fuel an alternate pressure recommendation. I keep my tires at 32 lbs cold and everything works so much better. I put on cross contacts and drove cross country (USA) and had a smooth and comfortable trip. You won't find those alternates in the manual or the door jam, only the fuel lid. I have a 2016 GLC 300 by the way. Love it.

I have a 2017 GLC300 RWD with Scorpion Verde 235/60 R18. The front tires are wearing on the outside edge much faster than the rest of the tire.

I bought two new tires, rotated the back to the front as those tires weren't showing the wear on the outside, and put the new tires on the back. Now, it appears the front tires are wearing on the outside again. On this model MB is this a tire issue or a camber/car issue?

It seems blame is being placed on both. If it is a car issue, is there a repair fix under recall?

Hi Friends,

My GLC 300 which drove around 9000+ miles is already due for two front tires to be replaced. Considering same Pirelli Scorpion Verde All Season Run Flat Tires for now. But any ideas about Continental Cross Contact LX Sport All Season Run Flats?

Appreciate your inputs.

Thanks,
Reddy
I strongly suggest a set of Michelin Crossclimate SUV. Had a set on my previous GLK 220d. Outstanding in all conditions, heavy snow, scorching heat, wet. Comfort is top notch. My wife said I did something to the suspension. Very quiet as well, good braking performance. Better in every way than the other tyres I used (Good Year for summer and nokian WR3 for winter)

I know this is old, but thank you for sharing the details. For the lug bolt size, is the 23mm the thread length or outer diameter of head? My Mercedes dealer is being less than helpful, so I am trying to just purchase generic lug bolts. If I can confirm the thread length, I am on my way. Cheers!

I wanted to thank the Lowcountry Joe for his detail on the spare tire options he provided....so helpful. I followed his guidance and wanted to add a few more details in case another forum member is going down this path.
I also had poor experience with the Scorpion run flats ( 19" wheels on my GLC) wearing rapidly enough that by the time I got to 31K miles I had replaced 3 pairs already and needed a full set of 4. During this time each dealer visit involved $550 for the pair and another $159 for alignment. My 'new tire purchase' @ 31K miles were for 4 non run-flats, out the door for $450.
I am now @ 45K miles, car rides nice, still good tread for tires less than half the cost.
But the whole spare thing has my wife reluctant to take the car on any long trip, hence this post was a lifesaver.
The W251 compact spare totally worked...it fit nicely under the rear and had plenty of clearance when mounted on the car...I acquired it from ebay. New lug nuts I grabbed from ebay....M14X1.5 'ball seat' - I went with 24mm length as I could get them easy and cheap. Found a used Mercedes OEM 17mm lug wrench on ebay and bought the highest rated 12V inflator that fit under the back area from Amazon. I grabbed an inexpensive scissor jack that would raise 15" and then threw in a 6" block of 2x4 as a spacer. I added a large, heavy duty 50 gal trash bag (for the removed tire) and a few gloves into the mix and then printed off pages 480 - 486 from a 2006 Mercedes r350 (w251) owners manual ( explaining how to inflate, mount, etc.) and put it all underneath. I'm into it for about $160.
Downside....it is heavy-ish...I did for sure add some weight to the car. Haven't seen a big change in mileage but I'm sure it's there.
Upside, we can take the car on longer trips now....hoping to never have to use this stuff but it's there just in case.
Hope this helps....and thanks tons to OP for getting me down this path !

My first post!! I have a 2018 GLC 250d, I have just clocked up 46000 Kilometers (reasonable millage) and shortly will need to replace the four run flat tyres. 255/45/r20 Pirelli Scorpion Verde I am seriously considering change them to NON run flats due to harsh ride, (and cost) has anyone else done this and how does it affect the 4matic transmission if at all. Having normal tyres and a spare would suit better on long trips.
