What are the reasons for tires being prone to blowouts on highways?
2 Answers
Here are the reasons for tire blowouts on highways: 1. The brake pads generate heat due to friction during driving, leading to tire blowouts. 2. Before entering the highway, some vehicles have insufficient tire inflation, causing prolonged friction with the ground and heat buildup, which results in tire blowouts. 3. The brakes on the tires are adjusted too tightly, especially the front tires. When the driver brakes in an emergency situation, the huge inertial force generated will concentrate on the overly tight tire, making it prone to blowouts. 4. If the brakes are not adjusted accurately, with one side of the vehicle's tires being too tight and the other too loose, it can lead to uneven friction—half rubbing and half not. This also generates high temperatures and heat, causing tire blowouts.
The main causes of tire blowouts on highways include intense friction between the tires and the road surface during high-speed driving, generating excessive heat that leads to a rapid increase in tire pressure. Slight overloading or aging tires can easily rupture under these conditions. Having driven long distances frequently, I've witnessed numerous blowout incidents, many occurring during summer or extended trips when high tire temperatures, combined with wear cracks or weak patches, can't withstand the pressure. Non-standard tire pressure is also hazardous—too high reduces elasticity, making tires stiff and prone to bursting over potholes, while too low causes sidewall deformation and accelerated heat damage. Prevention is straightforward: before every highway trip, check tire pressure for accuracy, inspect the surface for cracks, and replace old tires every six months for safety. During prolonged highway driving, stopping every two hours to cool the tires is advisable. Never overlook these details—safe driving ensures family safety.
