This car is equipped with two kinds of tires, one is 225/50r 17 and the other is 225/45r 18. 225/50r 17 indicates that the tire has a width of 225mm and a flat rate of 50, and can be mounted on a rim of 17 inch. A flat ratio of 50 means that the sidewall height is 50% of the tread width. Then, the greater the flattening value, the thicker the tire when viewed from the side, the smaller the flattening value and the thinner the tire when viewed from the side.

When you change the tire of your car, riders need to see the tire size clearly, and the tire size will be written on the side of the tire. It is recommended that riders change their tires every four years. Even if the mileage is less in four years, they still need to replace it, because the tire rubber will age after a long time. When buying new tires, you should see the date of production of the tires clearly. If it is more than three years, don't buy it. The date of production of the tire is also written on the side of the tire. If the tire production date is 10 19, it means that the tire was produced in the week of 20 19. When buying a tire, don't buy it if there is no production date on the side of the tire. This kind of tire was deliberately worn out by the store to hide the production date. When installing the tire, pay attention to distinguish the inside and outside of the tire and look at the outside from the outside. After changing the tire, it is necessary to do a new dynamic balance so that the wheel will not shake at high speed.
