An alarming sign showed up on the screen of my car, which wasn't familiar to me, but I promptly understood what it was meaning from its design. It was telling me about the low pressure of tires. It would be exacting work to figure out the design which can be easily and correctly recognized by people.
Anyway, I brought my car to a tire shop and had all the tires checked. The right front tire was slightly low-pressured. It was taken off and was sunk into water to detect the puncture, but no puncture was found. The air would be discharged bit by bit for long hours. Nitrogen gas was infused into all the tires and the inspection was done.
The mechanic pointed out the tire wear at the same time. It's 23 months since the purchase and I drove the car almost 70000km though I used winter tires during winter. I have to think about purchasing new tires next spring.
