Should you replace the repaired tires? Let’s talk about the tires.

The general service life of tires is about 3 years and 8W kilometers. This is not absolute, because the wear and tear of tires has a great relationship with the road surface. If the road surface is smooth, the service life will be longer. If the road surface is smooth, the service life will be longer. If the road is bumpy or gravel, the service life of the tires will definitely be reduced. Let’s talk about the most common judgment points when tires need to be replaced. The general service life of tires is about 3 years and 8W kilometers. This is not absolute, because the wear and tear of tires has a great relationship with the road surface. If the road surface is smooth, the service life will be longer. If the road surface is bumpy, uneven or broken The service life of tires on stone roads will definitely be reduced. Let’s talk about the most common judgment points when tires need to be replaced.

1. Judgment of tire tread depth: The quality of tire tread directly affects the grip of the tire and the stability of the vehicle. If the tire tread is too thin or even nonexistent, the braking distance of the vehicle will be longer, and the vehicle will easily slip when driving in rainy days. . Therefore, tire tread depth needs to be checked regularly. Generally, each tire will have a tire pattern wear mark on it. If the tire wears to this mark, the tire needs to be replaced, that is, the tire tread depth is less than 1.6MM. As a reminder, it is best to replace coaxial tires together, because the new and old tires have different tread depths and different grips, which may cause the vehicle to deviate and slip.

2. Judgment of tire rubber aging: In fact, the number of kilometers driven by family cars every day is not very many, so not many are worn to the pattern limit marks, but there are many signs of tire aging, and tire rubber is the most aging. What is common is that the surface of the tire appears cracked and has many small cracks. This phenomenon is called tire cracking. Because tire rubber requires a certain hardness, there is a process called vulcanization during manufacturing. Vulcanized rubber increases its hardness, but it will age over time. Therefore, the general service life of tires is about 3 years.

3. If there are bulges or scratches on the tire sidewall, it needs to be replaced, because bulging means that one or more of the steel wires inside the tire are broken, causing the rubber to be unable to withstand the pressure inside the tire, so it will When a bulge occurs or the sidewall is scratched, it is also very dangerous, because the tire sidewall is the weakest part of the tire. Scratches will destroy the strength of the tire sidewall, causing the rubber to become thinner in one part of the tire sidewall. After the rubber is thinned If the tire cannot withstand the pressure inside the tire, it may burst. Generally, bulges and scratches are caused by external force damage to the tire. Therefore, it is recommended that car owners do not pull too far to the side when parking to prevent the tire sidewall from rubbing against the curb and causing the tire to bulge. If there are bulges or scratches, the tires need to be replaced to prevent the vehicle from blowing out due to continued use.

4. The tires have abnormal wear and tear, commonly known as: "tire eating" and "tire chewing". Tires also need to be replaced at this time, because abnormal tire wear will lead to excessive tire pressure, insufficient tire grip, and longer braking distances. Failures such as vehicle slippage occur. The fault point that causes tire eating and tire chewing is that the vehicle's four-wheel alignment data is incorrect, so after replacing new tires, you need to do a new four-wheel alignment and adjust it to the standard data.
