Nowadays, with the gradual tightening of driver's license and traffic regulations, many car owners attach great importance to driving safety, especially in the summer when the temperature is relatively high, which is a high incidence period of tire accidents. If there are scratches on the sidewall of our car's tires, can we get on the highway? I believe this issue has troubled and troubled many friends, as many car owners are not familiar with the structure of tires, so any scratch on the tire wall can be very tense. Actually, can I get on the highway with scratches on the tire wall? Can the tires continue to be used? There are also many situations that need to be analyzed based on specific circumstances.
A tire is not a single layer of rubber, it is a combination of multiple layers of rubber and some composite materials. The innermost layer belongs to its airtight layer, with a support layer and cord layer in the middle, and a rubber layer in the outermost layer. Let's take a closer look, and its sidewall is indeed much thinner than the tire crown, so sidewall scratches are more serious damage to the tire than the crown. Can we run on the highway when our tire sidewall is injured? We can break open the scratch and take a look. If it is not deep enough to reach the cord layer, it means that the side wall cord has not been broken. In fact, this kind of damage does not have a significant impact on the safety of the tire.
For example, the tire fabric layer is like the layer that bears weight and strength when our house is built. Therefore, if your house leaks water, white lime will fall off, but the house will not collapse and will not affect the structure and strength of the house. However, we still need to pay great attention to this point. Although some tires may not have open wounds on the sidewall, they may have suffered internal injuries. For example, if the tire wall is relatively firm, there will be no open scratches. However, as time goes on, the area where the tire is compressed may be stretched or broken due to the cord inside during compression, So after a long time in this area, it will gradually bulge. Once a tire bulges, regardless of whether your tire has any wounds or not, your tire must be replaced because the bulge point represents that the cord inside it has been damaged. Once a bulge occurs, the temperature may be too high at high speeds, the speed may be slightly faster, and if the compression is slightly more severe, it may cause a tire blowout.
So, after the sidewall of our tires is scratched or scratched, theoretically, as long as the tire cord is not damaged and there is no bulging, the tires are safe. If you are really worried about running on the highway, you can also take a more conservative approach, which is to put the front tire on the rear tire, so that you can drive with peace of mind. If your car has a high-quality full-size spare tire, you can replace the damaged tire. It is not a problem to use the removed tire as a low-speed emergency.
Finally, I would like to remind all car owners that although our tires may get scratched sometimes and we were fine at the time, over time, there may also be bulges in the scraped areas. Therefore, we should develop a habit of diligent tire inspection during our daily use. It is recommended that everyone check the tires once a week and a half a month to develop good driving habits to ensure our safety.
