When accelerating and braking, it depends on the grip of the tire. Take acceleration as an example. If the two front wheels are different, one has strong grip and the other has weak grip. When accelerating rapidly, those with weak grip will slip in place, and those with strong grip will turn forward and will definitely lean to the side with weak grip. So is the brake. When braking suddenly, it will lean to the side with strong grip. These are two extreme cases, even in normal driving, there will be deviation and the tire life will be shortened, so the tires on the same axle must not be mixed.
If other tires wear more or have a long service life, they need to be replaced in pairs. If the other tires are relatively new, you don't need to change them in pairs. Just change one tire. To give a rough reference standard, when the remaining life of a tire reaches one-third or even less of the total life, it needs to be replaced together. When the mileage reaches more than 70,000 to 80,000 kilometers, or the service life is close to more than four years, the general remaining life is not much. Look at the age first. No matter how much new tires are used, they should be considered for replacement after five years. How many kilometers does it take for the tire to wear to the limit? The wear degree of different brands of tires is different, and the wear degree is also different under different driving conditions, generally between10-150,000 km.
