ANSWER · B
When tire pressure is too high during high-speed driving, tire temperature rises, pressure increases, the tire deforms, body elasticity decreases, and dynamic load on the car increases. An impact may cause internal cracks or blowouts. When tire pressure is too low during high-speed driving, insufficient pressure can cause the tire body to "resonate," creating a huge resonant force. If the tire is not strong enough or already damaged, blowouts are likely. In addition, low pressure increases tire sinking, so the tire wall easily touches the ground during sharp turns. The tire wall is the weakest part, and contact with the ground can also cause blowouts. With low pressure, the tire-road contact area increases and tire temperature rises, making blowouts likely.
