Change tyre

It was a good day to change the tire from the normal to studless winter tyre.
I know it's hard to handle nuts to release or fasten from the bolts.
I wanted to buy an electric impact wrench to help the work easier and faster.

I've just got it at the DIY home center and let it be done economically.
I paid for it about ¥5,000 and expect it will help me more than 10 times after
years.
I don't want to drive on the snowy road but need to be prepare for winter days.
