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

Driving at high speeds with underinflated tires may lead to the following consequences: The friction between the tires and the road surface increases exponentially during high-speed driving, causing the tire temperature to rise. This makes the tires softer and increases the risk of a blowout. Tire pressure refers to the air pressure inside the tire, which is essentially the 'blood pressure' of the car. The level of tire pressure plays a crucial role in the vehicle's performance and power, serving as an indicator of the car's load capacity. The load a car can carry depends significantly on the tire pressure. Hazards of abnormal tire pressure include: 1. Reduced friction and adhesion of the tires, affecting braking performance; 2. Steering wheel vibration and deviation, diminishing driving comfort; 3. Accelerated wear of the central tread pattern, shortening tire lifespan; 4. Increased body vibration, indirectly affecting the lifespan of other components; 5. Excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the car during driving.
I think driving on the highway with low tire pressure is extremely dangerous because the tires deform significantly, generating continuous friction and heat during rolling, which can easily lead to a blowout—a potentially fatal situation. I've seen many accident reports where insufficient tire pressure on the highway caused loss of control and rollovers. Additionally, when driving at high speeds, the car may feel like it's drifting or shaking, with unstable steering control. In case of sudden turns or avoiding other vehicles, delayed reactions can be deadly. Therefore, for safety, I always use a simple tire pressure gauge to check all four tires before hitting the highway, ensuring they are within the standard range. Don't take chances—if you find the pressure too low, it's best to pull over to inflate them or call for assistance. Don't push your luck; life is precious.
Driving with low tire pressure on the highway first leads to significantly increased fuel consumption. This is because the increased friction between the tires and the road forces the engine to work harder. I've calculated it can cost dozens of yuan more in fuel per month. Secondly, it causes uneven tire wear - the center part gets compressed excessively and wears out faster, leading to another expense of hundreds to thousands of yuan for new tires. It also affects ride comfort, making the car noticeably bumpier at high speeds, which tires the body and increases accident risks. Therefore, I believe regular tire pressure checks are crucial. Carrying a small tire pressure gauge makes this quick and easy, taking just a minute or two.
