Car tires are an important part of the car, which directly touches the ground, bears the weight and power of the car, and affects the driving performance and safety of the car. Therefore, replacing tires in a timely manner is a must for every car owner. So, how often do car tires need to be replaced? Is there a uniform standard?
In fact, there is no fixed answer to the replacement cycle of car tires, it depends on a variety of factors, such as the brand of tires, quality, service life, mileage, driving habits, road conditions, and so on. However, we can judge whether the tires need to be replaced according to some judgment methods to ensure the normal operation of the car and safe driving.
A tire wear mark is a small bulge reserved by the tire manufacturer on the tire tread to indicate the degree of wear of the owner's tire. In general, the height of the tire wear mark is 16 mm, when the tire tread is smoothed to the level of the wear mark, it means that the tire has reached the limit of wear and needs to be replaced immediately. If you continue to use it, the grip, drainage, and comfort of the tire will be greatly reduced, and there may even be dangerous situations such as punctures.
Tire aging refers to the phenomenon of tire performance decline, cracks, hardening, and brittleness due to the natural aging of rubber materials or the influence of the external environment during the use of tires. After the tire ages, the elasticity, toughness, and heat resistance of the tire will be reduced, which is easy to cause tire deformation, cracking, puncture and other failures. Generally speaking, the service life of tires is 3-5 years, and if it exceeds this time, even if the tires are not significantly worn, they should be replaced in time to avoid potential safety hazards.
During the driving process, the tires will inevitably encounter some unexpected situations, such as tire nails, tire bulges, tire scratches, etc. These conditions will affect the normal use of tires and even endanger driving safety. Therefore, car owners should regularly check the damage to the tires and replace them as soon as possible if they are found to have the following conditions:
Tire nail: If it is a tire tread nail, you can consider using a professional tire repair tool to repair the tire, but if it is a tire sidewall nail, it must be replaced, because the structure of the tire sidewall is relatively weak, and it is easy to leak or puncture after repairing the tire.
Bulging tires: If the tires are subjected to severe impact while driving, such as hitting curbs, stones, etc., it may cause the ply layer inside the tires to break, causing the tires to bulge. Bulging tires are very dangerous because the air pressure and temperature inside the tires can cause the bulging area to expand, eventually causing the tire to burst.
Tire scratches: If the sidewall of a tire is scratched by a sharp object or a sharp object, it may damage the ply layer of the tire, causing a flat tire or a puncture. If the scratch is shallow, only a little skin is broken, and the cord layer is not damaged, you can not change it temporarily, but you should always observe whether the scratch has expanded. If the scratch is deep and the cord is exposed, it must be replaced.
In short, there is no fixed answer to the replacement cycle of car tires, but there are some judgment bases, and car owners should check and replace tires in time according to the wear marks, aging phenomena, damage, etc., to ensure the driving performance and safety of the car. At the same time, car owners should also pay attention to developing good driving habits, avoid sharp acceleration, sharp braking, sharp turns, etc., reduce unnecessary wear and tear of tires, and prolong the service life of tires.
