Why do car tires break easily in rainy days?

There are three reasons why tires are often injured in rainy days:

1. When cutting rubber products with a knife, it is very laborious to cut directly, and it becomes easy to pour some water. Usually, if the tire is crushed to a stone or a sharp obstacle, it will not be damaged, but it is different in rainy days, and it is easy to scratch the tire.

2. On rainy days, the ground is slippery and nails are soaked in rain. Because of the fluctuation of water, the probability of puncture is increased.

3. When driving in rainy days, due to the influence of weather and road water, the driver's visual effect will be reduced, and it is more likely to cause tire scratches.

Many card friends reported that after a flat tire was repaired at the maintenance station, it still leaked slowly. The maintenance personnel said that the tire was vulcanized from several parts, such as the airtight layer, the cord, the belt, the crown belt and the tread rubber. After the nail pierces the tire, air will enter the gap between the layers of the tire through the nail hole because the tire rolls.

Ordinary tire repair only repairs the innermost layer of the tire, that is, the airtight layer. After the repair of the airtight layer, it can only ensure that the air inside the tire does not leak to the outside. However, there is no need to worry about the fact that the air entering the interlayer gap will continuously leak and bubble.
