Can glue be used to repair scratches on the tire tread?

[StSarah]

Glue should not be used to repair scratches on the tire tread. Below are some tire maintenance precautions: 1. Regularly check tire pressure: Tire pressure is a crucial factor affecting tire lifespan. It should neither be too high nor too low; always inflate according to the vehicle's recommended pressure. In summer, try to keep the tire pressure slightly lower. In winter, ensure the tire pressure is slightly higher than in summer due to thermal expansion and contraction. 2. Inspect wear patterns: Some vehicles may experience uneven tire wear. Frequently check the inner side of the tires for abnormal wear, focusing on whether the tread depth is consistent on both sides. 3. Remove foreign objects promptly: Debris in the tire tread poses potential hazards and can be ejected while driving. 4. Perform wheel alignment regularly: If the vehicle pulls to one side or exhibits abnormal steering, have the wheels aligned immediately to prevent further issues. Wheel alignment ensures even force distribution across all four tires, preventing excessive wear.
