The normal lifespan of a tire is reached, and it must be replaced with four tires at the same time, or at least two tires at the same time. In reality, a lot of tires are not replaced due to wear or aging, but rather due to external damage, such as scratches, punctures with thick nails, or punctures on the sidewalls. Do we also need to replace the tires in pairs in this situation? Is there any adverse effect when switching to a different one?

Not necessarily, it depends on the degree of wear of other tires and whether to replace them in pairs according to the actual situation. If other tires are worn out more or have a longer service life, they need to be replaced in pairs. If other tires are still relatively new, there is no need to replace them in pairs, only one tire can be replaced. A rough reference standard is that when the remaining life of a tire reaches one-third or even less of its total life, it needs to be replaced together. When the mileage reaches 70-80000 kilometers or more, or the lifespan approaches four years or more, the remaining lifespan is generally not much. Let's first look at the lifespan. No matter how much a new tire is used, it should be considered for replacement after 5 years. How many kilometers does it take for tires to wear to their limit? The wear resistance of different brands of tires varies, and the degree of wear also varies depending on the driving conditions, usually between 100000 and 150000 kilometers.

If other tires are worn out too much and not replaced in pairs, replacing only one new tire may cause some problems, such as driving or braking deviation, especially on wet and slippery roads. This is because the grip, friction coefficient, and height of new and old tires are different, which can lead to the above situation. Due to the different drainage capabilities of tires, there is a lot of rain in summer, and it is also easy to slip and deviate when driving in water.

Can different brands of tires be mixed? It can be mixed, but the two tires on the same axis must be ensured to be the same. That is to say, the two front wheels must be the same and cannot be mixed, the two rear wheels must be the same and cannot be mixed, but the front and rear wheels can be different and can be mixed. Due to different tire brands and patterns, the performance of each item must also be different. When accelerating and braking, it relies on the grip of the tires. Taking acceleration as an example, if two front wheels are different, one with strong grip and the other with weak grip, during sudden acceleration, the weak grip will slip in place, while the strong grip will rotate forward, which will definitely lead to deviation towards the side with weak grip. The same principle applies to braking, as when braking suddenly, it will deviate towards the side with strong grip. These are two extreme situations. Even during normal driving, there may still be deviation, and the lifespan of tires will also be shortened. Therefore, tires on the same axis must not be mixed.

Normally, when using a car, the front tires are generally more worn than the rear tires. If the tires have never been rotated, the front wheels can be replaced twice before the rear wheels can be replaced once. Therefore, to extend the lifespan, it is necessary to regularly replace the tires, usually every 20000 kilometers. This can make the four tires wear evenly and have almost the same lifespan. When replacing tires, all four can be replaced at the same time.
