Will 2022 GLC 300 spare tire fit 2018 GLC 300?

Hi there,
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.

Will 155/80/19 spare tire be fine for my 2018 GLC 300? I have located one and want to make sure it will fit. it is 5x112 bolt.

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.

Thank you! I visited this site as well. Now I am seeing pictures that this 155/80/19 tire will not let the floor panel to close. I have to figure that part out before buying it. The rim is A167 400 03 00. Do you know if this will be fine with the 2018 GLC 4Matic?

I remember a similar thread about OE spares fitting under the floor.

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.
