I have been doing my own car tire changes (stock tires / snow tires).
I'm posting the video on YouTube as a note for myself (note: audio is available).
The purchase of the necessary equipment is sufficient for the cost of one tire change at a car dealership, which is very cost-effective.
More than that, changing a tire is "fun".
Well, maybe the reason why I feel happy is that I only do it twice a year (it's hard work if I do it as a job).
I think if it's fun, it should be shared with everyone.
However, when I tried to teach my wife how to change a tire, she politely refused.

After I said, the family members except me said
"We are going to go to the dealership as normal"
