1. Tread depth

胎面花纹的厚度应大于1.6毫米。如果在低摩擦的潮湿路面上行驶，请确保胎面花纹的厚度是上述值的两倍。尽管您可以从那里学习并购买量规来测量胎面花纹的厚度，但是老司机经常使用流行的方法来估算胎面花纹的厚度。费用为$ 1。向上插入胎面槽，因为从边缘到顶部的距离为1-2 mm。此时，您可以看到胎面花纹的总厚度不足。

The thickness of tread pattern shall be greater than 1.6 mm. If driving on wet roads with low friction, make sure that the tread pattern thickness is twice the above value. Although you can learn from experts and buy gauges to measure tread thickness, older drivers often use popular methods to estimate tread thickness. The cost is $1. Insert tread groove upwards as the distance from edge to top is 1-2 mm. At this point, you can see that the total thickness of the tread pattern is insufficient.

2.花纹磨损指示线

2. Pattern wear indicator line

与过去的旧产品相比，新的轮胎设计更加人性化：胎面花纹磨损指示器。如果轮胎是新轮胎或磨损程度很低，则几乎看不到这些指示，但是当磨损达到一定程度时，您会发现这些线条隐藏在胎面花纹沟中。胎面花纹磨损指示器线是扁平橡胶条，其垂直嵌入胎面的垂直胎面槽中。如果检查轮胎并偶尔发现一两个指示线，则胎面花纹会明显变薄。在这种情况下，在湿滑的路面上行驶时要小心。如果您可以清晰地看到轮胎上几乎所有的指示线，则意味着您需要尽快更换轮胎。

Compared with the old products in the past, the new tire design is more humanized: tread pattern wear indicator. If the tire is new or has low wear, you can hardly see these indications, but when the wear reaches a certain level, you will find these lines hidden in the tread groove. The tread pattern wear indicator line is a flat rubber strip embedded vertically into the vertical tread groove of the tread. If the tyre is checked and occasionally one or two indicator lines are found, the tread pattern will become significantly thinner. In this case, be careful when driving on slippery roads. If you can clearly see almost all the indicator lines on the tire, it means that you need to change the tire as soon as possible.

3.轮胎胎侧裂纹

3. Tire sidewall crack

并非所有轮胎问题都集中在胎面上，轮胎胎侧也存在一些问题。检查轮胎的侧壁是否有明显的裂纹或割伤。这些小凹槽表明轮胎将来可能会漏气，更糟糕的是，轮胎可能会爆裂。这些轮胎的故障是我们要避免的事情。因此，如果轮胎侧壁上的裂纹看起来更严重，则将车辆开到修理厂并尽快更换轮胎。

Not all tire problems are concentrated on the tread, and there are also some problems with the sidewall of the tire. Check the sidewall of the tire for obvious cracks or cuts. These small grooves indicate that the tire may leak in the future and, worse, burst. These tire failures are something we need to avoid. Therefore, if the cracks on the sidewall of the tire appear to be more severe, take the vehicle to the repair shop and replace the tire as soon as possible.

4.轮胎胀大和胀大

4. Tire expansion and expansion

由于缺乏强度，轮胎的外表面可能会比普通轮胎的表面升高并且起泡更多。轮胎也面临类似情况。如果您未能及时运送到修理厂并发现轮胎故障，则胎面强度不足的零件可能会突然高速破裂。轮胎破裂甚会对驾驶员和乘客造成严重伤害。

Due to the lack of strength, the outer surface of a tire may be raised and blistered more than the surface of a normal tire. Tires face a similar situation. If you fail to deliver it to the repair shop in time and find a tire failure, parts with insufficient tread strength may burst suddenly at high speed. Tire rupture can even cause serious injury to the driver and passengers.
