I often see comments like this: tires should be replaced after 5 years of use and 80,000 kilometers. So this creates an illusion: if the tire has aged seriously for two or three years and needs to be replaced, it means there is a problem with the tire quality. If the tire has run for 50,000 to 60,000 kilometers and the pattern wear is serious, it means the tire quality is not good. Some tires have been used for more than two years, the tire tread is peeling, the tire quality is really rubbish, and the same new tires must be replaced.
Used for 5 years. Tires need to be replaced only after running 80,000 kilometers. I don't know where this statement came from. Of course, this does not include crashes, bulges and other special circumstances. Regarding tire replacement, let's see what the tire companies have to say?
Driving with a deflated tire, even for a short distance, can damage the tire. If the damage is limited to the tread, most punctures, nail holes, or other cuts no larger than 1/4 inch (0.64 cm) can be repaired.
Punctures larger than 1/4 inch (0.64 cm) in the sidewall or tread shall not be repaired, nor shall they be repaired if the tread is worn below 1/16 inch (0.16 cm). That means it needs to be replaced.
Damage to the bead, carcass, and steel belt cannot be repaired, and holes with a diameter exceeding 6 mm (cold patch film) or 8 mm (mushroom nails) cannot be repaired. When ordinary tires are used in winter, the remaining tread pattern of the tire must not be less than 50%, and the tread scale must be replaced if it is below the wear line.
All tires (including spare tires) that are more than 10 years old should be replaced, even if they appear to be serviceable and have not worn to the wear mark.
When it comes to tire replacement, the following tread depths are recommended: 3 mm for summer tires and 4 mm for winter tires.
Different tires perform differently, and as wear begins, performance changes and the differences become more pronounced. This is because tire performance is affected by many factors, such as carcass design, raw materials, rubber formula, tread design and tire groove shape. Modern tire technology ensures excellent performance and grip throughout the life of the tire, from the time it leaves the factory until it reaches specified wear limits.
There are many factors that affect tire performance, such as carcass design, raw materials, rubber formula, tread design, tire groove shape, etc. These factors affect how a tire performs throughout its life, until it reaches its wear limit. New tires do not all perform the same, and due to the different designs of the tires, the differences in their performance become more pronounced as wear increases.
Don't use age and kilometers to limit tire performance!
