How can I check how much I used my car tires?

A. 1

If you want to see how worn the tire is, look at the wear limit on the groove in the middle of the tire
If the tire is worn near the wear limit, it must be replaced.
Sometimes it's hard to find the wear limit.
In that case, you can use a 100 won coin.
Usually, it is normal that you can't see the shape of the satgat when you insert a 100-won coin upside down into the tire groove.
If you see more than two-thirds of the tires, it is recommended that you get them checked and replaced.

It's detailed here.
I often don't know the wear limit, so I think you can refer to the picture on this blog.
