Scraping the tire when parking by the side is serious. It causes significant damage to the tire, as the sidewall is the thinnest part and may suffer catastrophic harm, leading to bulges or ruptures. Once the tire sidewall bulges, even if it hasn't ruptured, it must be replaced immediately; otherwise, it poses a high risk of blowout, threatening safety. Tires are one of the most critical components of a vehicle, so special attention must be paid to their maintenance: 1. Maintain distance: Keep a safe distance when driving at high speeds to avoid unnecessary or frequent braking, reducing tire wear. Also, for safety, monitor the tread depth; tires with nearly worn-out treads have reduced friction with the road, leading to longer braking distances—avoid high-speed driving with such tires. 2. Proper loading: There is a direct relationship between tire load and pressure. Overloading is similar to underinflation and can cause tire damage. Frequent overloading reduces tire lifespan by 20%-50%. Incorrect loading methods can also lead to uneven tire wear, causing some tires to bear excessive loads and shorten their lifespan. 3. Ensure proper pressure: Tire pressure is vital. The inflation pressure must comply with national standards for different types and specifications of tires. Regularly check tire pressure; both overinflation and underinflation can cause irregular wear, tread groove cracking, cord breakage, ply separation, and tire blowouts. For sustained high-speed driving, increase the pressure by 5%-10% above the standard. Note that tire pressure rises with temperature after driving—do not release air in this case. 4. Tire rotation: Rotate tires appropriately and timely (check during vehicle primary and secondary maintenance) to ensure even wear and extend lifespan. Install slightly larger-diameter tires on the outer wheels. 5. Tire selection: Avoid using retreaded tires on the front wheels. Prefer tires with vertical tread patterns for the front wheels and horizontal tread patterns for the rear wheels.
