Whether a damaged tire sidewall can be repaired depends on the extent of the damage. Here are the details: 1. If the sidewall is severely damaged, it cannot be repaired and must be replaced. 2. If there is only a small puncture and no obvious rapid air leakage, it can be repaired. Below are some tire maintenance tips: (1) Maintain a safe distance when driving at high speeds to avoid unnecessary or frequent braking, which can damage the tires. Also, for safety reasons, pay attention to the tread depth. Tires with nearly worn-out treads have reduced friction with the road, leading to longer braking distances, so avoid high-speed driving. (2) There is a direct correlation between tire load and pressure. Overloading is similar to low pressure and can cause tire damage. Frequent overloading can reduce tire lifespan by 20%-50%. Incorrect loading methods can also lead to uneven tire load distribution, causing excessive wear on certain tires and shortening their lifespan. (3) Tire pressure is critical. The inflation pressure must comply with national standards for different types and specifications of tires. Regularly check tire pressure, as both overinflation and underinflation can cause irregular wear, tread base cracking, cord breakage, ply separation, and even tire blowouts. For sustained high-speed driving, the pressure should be 5%-10% higher than the standard. Additionally, tire pressure increases with temperature after driving, so do not release air at this time. (4) Rotate the tires appropriately (check during primary and secondary vehicle maintenance) to ensure even wear and extend their lifespan. Larger-diameter tires should be installed on the outer wheels. (5) Do not use retreaded tires on the front wheels. Front wheels should preferably use tires with vertical tread patterns, while rear wheels should use tires with horizontal tread patterns. (6) Replace tires when the wear reaches the tread wear indicators.
