5 signs about tire failure

  Just as your feet feel sore after every hike, the tires have to bear pressure from the road every time you drive.Tire wear often does not mean that there is a problem with your driving habits. This phenomenon is a fact that is inevitable in normal driving. Tires will gradually wear and age, and eventually lose their grip.If the tire fails during the driving process, the consequences will be catastrophic. It can cause the vehicle to lose control and make you stay in a remote area off the beaten track, making it difficult to reach the destination in a short time.When you clearly understand whether your car’s tires are deformed and whether their performance is degraded, you can replace them with new tires in time to avoid failures.Of course, if there is a maintenance technician who can check your vehicle regularly, they can inform you whether you need to replace the tires, but we can complete the simple vehicle inspection tasks such as judging whether the tires are deformed, so as to save the time of going to the auto repair shop.Here we will give five early warning signals (the five situations are of equal importance) to remind you that it is time to replace the tires.
  1. Tire tread pattern depth
  The thickness of the tread pattern must be greater than 1.6 mm. If you often drive on wet and slippery roads with low friction, it is best to ensure that the tread pattern thickness is twice the above value.You can learn from professionals and buy a gauge to measure the thickness of the tread pattern; however, veteran drivers often use a widely circulated trick to roughly estimate the thickness of the tread pattern. It does not need to spend any money, that is, to take out a A one-dollar coin is inserted into the tread groove along the top of the national emblem. Because the distance between the edge of the coin and the top of the national emblem is between 1 and 2 millimeters, if you can still see the entire national emblem at this time, it means that the tread pattern thickness is insufficient. .The next thing to do is to drive the car into the repair shop and have the technicians replace you with a new set of tires.
  2. Tread pattern wear indicator line
  The new tire has one more humanized design than the old-fashioned products in the past: tread pattern wear indicator line.When the tire is very new or the degree of wear is very low, these indicator lines are hardly noticed, but when the wear reaches a certain level, these indicator lines hidden in the tread gully appear.The tread pattern wear indicator line is a flat rubber strip, which is embedded in the tread gully perpendicular to the longitudinal direction of the tread.When you check the tires and occasionally find one or two indicator lines, it means that the thickness of the tread pattern has been reduced a lot. In this case, you must be extra careful when driving on slippery roads. In addition, you can pass the coin detection above. Method to confirm whether the tread thickness reaches the critical value twice.If almost all the indicator lines on the tire are clearly visible, it means that you need to replace the tire as soon as possible.
  3. Tire sidewall cracks
  The problems on the tires are not all concentrated on the tread, and there are also some defects in the sidewall of the tire.Fortunately, it is very convenient for us to visually inspect the tire sidewall problems manually: by looking for the cracks and cuts on the tire sidewall that are directly visible to the naked eye.These small grooves indicate possible leaks on the tires in the future, or worse, even cause tire bursts. These tire failures are what we desperately hope to avoid.Therefore, when the tire sidewall cracks seem to be serious, it is the best policy to drive the vehicle to the repair shop at the fastest speed to replace the tires.
  4. Bumps and blisters on tires
  In some cases, the outer surface of the tire may not be strong enough, resulting in bumps and blisters that are higher than the normal tire surface.This is like an aneurysm in a blood vessel. When a patient learns that he has an aneurysm, he will definitely go to the hospital immediately to prevent the aneurysm cyst from breaking the blood vessel.Tires are also facing a similar situation. If you fail to send the vehicle to a repair shop in time to detect tire failures, areas with insufficient tread strength are likely to cause sudden bursts, and tire bursts under high-speed driving may even cause drivers and passengers to appear. Serious injuries.Remind again to always pay attention to bumps and blisters on the tires.
  5. Excessive vibration and jitter
  A certain amount of jitter is inevitable when the vehicle is moving forward, especially in poor road conditions.When you have a certain driving experience, you can judge by feeling yourself what kind of jitter is within a reasonable range, and what kind of jitter indicates that the vehicle is malfunctioning.There are many reasons for vehicle jitter. It may be that the tires are axially offset or unbalanced in force, or there may be problems with the shock absorber.But jitter may also indicate that there are some problems inside the tire; even if the tire is not the root cause of vehicle jitter, jitter will damage the performance of the tire and cause tire problems soon.Therefore, if your car has a serious jitter, especially on a road with good road conditions, immediately drive the vehicle to the repair shop for inspection.Always keep in mind that a greater degree of jitter is often a precursor to vehicle failure.
