Question 2022 GLC Spare Tire / Non Run Flats

We put on about 2000 miles on our new 2022 GLC AMG 43. Love the car. Car came with the 21" tires that i thought were run flats and was told by the salesman they were (Which is why there is no spare) - However, recently had a nail removed and the tire plug and patched I quickly realized the tires (Continental ContiSportContact 5P) are NOT run flats.

I called MB dealer and they do not have a spare for this vehicle we can order. So i am curious what people were doing. I would feel better if i could find a spare that would work just in case, but now I'm a bit concerned since i don't have run flats and no spare.

The 20 and 21 MY had a spare tire kit as an option for $200 . Search on this forum ,you will find something . You may need to remove some of the lining under the trunk cover .

It appears something in the boot changed in 2022, and the sizing is now different. Trying to see if the dealer is able to option the spare after the fact seeing that these tires are not run flats from factory.

Check in your trunk. There should be a tirefit kit if it came with non-RF tires. It's a compressor with a can of tire sealant for emergencies. This is how the 63 models come since they don't have RF tires. It's either tucked away under the floor of the trunk or in a pouch velcroed to the trunk lining. I have the latter in my C63.

Just triple-checked and i dont see anything other than a plastic crate. Bizarre. Tempted to drive up to the dealer to ask or order the kit. I feel more comfortable having something that could help in a pinch.

edit: I found it! You were right @superswiss. under the floor there is a hidden plastic compartment on the left side containing exactly what you mentioned! A pump and some sort of sealent that connects to pump. I feel much better about not having a spare now. Thanks!

If they are indeed not runflat, then yes the tirefit kit was removed or forgotten. There is a runflat version of the Conti 5P, so check the sidewall. Conti calls it SSR (Self Supporting Runflat).

Found the kit! it was hidden and sealed away. I def have the 5P (non run flat) so this kit at least makes me feel better to have.
