Why Do Tires Blow Out on Highways?
2 Answers
The reasons for tire blowouts on highways: 1. Driving with underinflated tires; 2. Increased tire temperature. When the tire pressure is below the standard level, it indicates the tire is underinflated. Driving in this condition causes the friction between the tire and the road to multiply as the pressure drops, leading to a rapid rise in tire temperature, softening of the tire, and a sharp decrease in strength. At this point, if the vehicle is driven at high speed, it may result in a tire blowout. Increased tire temperature can also cause blowouts on highways due to the decline in the mechanical properties of the tire material. The rapid and repeated deformation of the tire during operation generates heat internally due to friction, while friction between the outer and inner tires, the tire and the wheel, and the tire and the road surface also contributes to a sudden rise in tire temperature.
I've been driving for ten years, and that tire blowout on the highway really scared me. There are many reasons for blowouts: common ones include tire pressure being too high or too low—friction from high-speed driving generates heat, and when the pressure expands too much, it's easy to burst; tire aging is also common, like in my case, where the tires had been used for several years, the tread was worn thin, and they couldn't withstand the summer heat; road debris like rocks or nails can cause stronger impacts at high speeds, leading to cracks upon contact; overloading is also a serious issue, as the weight of the car can overload the tires. I’ve made it a habit to check tire pressure and appearance monthly, ensuring there are no bulges or cracks, and I always buy reputable brands when replacing tires. Checking before hitting the highway is a must—safe driving relies on the details, so never underestimate tire maintenance.
