How often does the tire of the mixer change?

1. Tire tread depth
 
  The thickness of the tread pattern must be greater than 1.6 mm. If you are driving on a slippery road with low friction, it is best to ensure that the thickness of the tread pattern is twice the above value. You can learn a professional and buy a gauge to measure the thickness of the tread pattern; however, the old driver often uses a widely circulated method to roughly estimate the thickness of the tread pattern, that is, take out a one-dollar coin and follow it. The top direction of the national emblem is inserted into the tread groove, because the distance from the edge of the coin to the top of the national emblem is between 1 and 2 mm, so if the entire national emblem is visible at this time, the thickness of the tread pattern is insufficient.
 
2. Tread pattern wear indicator line
 
  The new tires have a more humanized design than the old-fashioned products of the past: tread pattern wear indicator. These indicators are hardly noticeable when the tires are very new or have a low degree of wear, but when the wear reaches a certain level, the indicator lines hidden in the tread gullies appear. The tread pattern wear indicator line is a flat rubber strip that is embedded in the tread groove perpendicular to the longitudinal direction of the tread. When you check the tires and occasionally find one or two indicator lines, the thickness of the tread pattern has been reduced a lot. In this case, you should be careful when driving on slippery roads. If almost all of the indicator lines on the tire are clearly visible, it means you need to change the tires as soon as possible.
 
3. Tire sidewall crack
 
  The problems on the tires are not all concentrated on the tread, and there are some problems with the sidewalls of the tires. Look for the cracks and incisions visible directly to the naked eye on the sidewall of the tire. These tiny grooves are indicative of possible leaks in the tires in the future, and even worse, the tires burst. These tire failures are what we hope to avoid. Therefore, when the sidewall crack of the tire looks more serious, it is the best policy to drive the vehicle to the repair shop to replace the tire at the fastest speed.
 
4. Bulging and blistering on the tire
 
  In some cases, the outer surface of the tire may be raised and blistered above the surface of the normal tire due to insufficient strength. This is like an aneurysm that appears in a blood vessel. The tire is also facing a similar situation. If you fail to send the vehicle to the repair shop to detect the tire failure in time, the area with insufficient strength on the tread is likely to cause a sudden burst. The bursting of the tires may even cause serious injuries to the driver and passenger.
 
  It is inevitable that a certain amount of jitter will occur during the vehicle's journey, especially under conditions of poor road conditions. When you already have a certain driving experience, you can feel what kind of jitter is within a reasonable range and what kind of jitter indicates that the vehicle is faulty. There are many incentives for vehicle shake. It may be that the tire has an axial offset or a force imbalance, or it may be a problem with the shock absorber. But the jitter may also indicate some problems inside the tire; even if the tire is not the root cause of the vehicle's jitter, the jitter will damage the performance of the tire and cause tire problems soon. Therefore, if your car has more serious jitter, especially if there is jitter on the road with good road conditions, immediately drive the vehicle to the repair shop for inspection. Keep in mind that a large degree of jitter is often a precursor to vehicle failure.
