Will 2022 GLC 300 spare tire fit 2018 GLC 300?
I have a 2018 GLC 300 without any spare. However, if I find a used spare tire/wheel from 2022 GLC, will that fit for 2018 GLC? I took a picture of a spare in 2022 GLC that says 145/80/19 and wondering if the same spec would be for 2018. Please let me know. Thanks.

1.4% diameter difference seems okay for spare.
But if you have a flat tire by a screw,
just pump some air and drive to home or to any repair shop. instead of replace tires on the road side.
You can drive 100+ miles with the screw by adding some air.
I just keep the air pump & tire plug kit in my trunk, without a spare.

If I remember the gist of the thread correctly, that spare should fit in a 2018, but you have to kind of crush the synthetic tire well to make it fit in a 2019 or newer.
2019 was the first year that you couldn't buy a spare and had to take run flats.
Don't quote me on the 155/80/19 specific size, though.
