Tire change

I changed my car’s normal tires to the winter ones. Usually I bring winter tires to a tire shop, and then a shop staff member changes the tires. It’s about 2,000 yen. However, I had to buy new winter tires this time because the old ones’ tread was too shallow for my car to run safely. I bought brand-new winter tires of Bridgestone. It cost over 170,000 yen. I think I have no choice to save my family’s cost of living in winter.
