Is it serious if the tire sidewall rubs against a curb?

[JakeRose]

It depends on the extent of the tire damage. If the damage is severe, the tire needs to be replaced or repaired before use. Here are some relevant tips for car tire maintenance: 1. Regularly check tire pressure: Inflate underinflated tires promptly and maintain consistent tire pressure. Otherwise, it can lead to rapid wear of low-pressure tires, increased driving resistance, higher fuel consumption, and may cause issues like directional deviation. 2. Avoid hitting obstacles: When driving at high speeds, hitting obstacles such as potholes can cause severe compression deformation between the obstacle and the tire near the rim flange. This may damage the tire's inner fabric cords, allowing air to escape through broken cords and form bulges. In severe cases, it can cause the tire sidewall to rupture, leading to sudden tire deflation.
