What are the potential consequences of driving at high speeds with underinflated tires?

Driving at high speeds with underinflated tires can lead to a significant increase in friction between the tires and the road surface, causing the tire temperature to rise. This makes the tires softer and drastically reduces their strength. The more underinflated the tires are, the greater the reduction in strength. If the vehicle continues to drive at high speeds under these conditions, it may result in a tire blowout. Even at low speeds, driving with underinflated tires can cause damage to the tires. If this issue goes unnoticed for an extended period, it can pose a threat to future driving safety. Relevant information about tire pressure is as follows: Standard: Tire pressure can be about 10% higher than the standard pressure, but it must never be lower than the standard pressure. This is because when driving at high speeds with underinflated tires, the sidewall tire cords undergo excessive bending deformation, generating heat rapidly, which in severe cases can burn the cords. Cause of wave deformation: This is due to the standing wave phenomenon of the tire. Specifically, when the part of the tire in contact with the ground deforms, the low pressure and high speed prevent the tire from returning to its original shape before the next contact with the ground.
I once drove on the highway and noticed the tire pressure was a bit low, which made the car feel particularly unstable and the braking performance worsened. When tire pressure is too low during high-speed driving, it increases friction, causing tire temperatures to skyrocket, which can easily lead to tire deformation or even a blowout. If a blowout occurs, the car may lose control, skid, or roll over—posing a terrifyingly high risk. I remember one time, my friend’s tire cracked due to insufficient pressure after prolonged highway driving, costing over a thousand yuan to repair. I recommend checking tire pressure before hitting the highway. The standard cold-tire pressure is usually listed on the door frame or in the manual. Maintaining proper tire conditions can prevent accidents and also save fuel.
Driving on the highway with low tire pressure is extremely dangerous. I once almost had an accident because I didn't pay attention. At high speeds, not only does tire wear accelerate, but it also affects handling—the car sways noticeably when turning. Low pressure makes the tire contact patch unstable and increases braking distance. If the car in front suddenly brakes, you might rear-end them. Economically speaking, fuel consumption increases because deformed tires create more resistance, and prolonged use accelerates tire aging, forcing you to spend unnecessary money on replacements. I personally check my tire pressure every month using a portable gauge—it's simple. Remember, don’t wait for the warning light to come on. Safety comes first, and timely maintenance can save lives and money.
