Final answer:
Under inflated tires are dangerous because they lead to increased wear, overheating, and reduced vehicle handling, which can cause accidents. They also negatively affect fuel economy. It is important to maintain tires at the manufacturer recommended pressure level for safety and efficiency.
Step-by-step explanation:
Why Are Under Inflated Tires Dangerous
When a tire is under inflated, its pressure is lower than what is recommended by the manufacturer. This condition can lead to a number of dangers including increased tire wear, overheating, and reduced vehicle handling. Under inflated tires have a larger contact area with the road, which generates more friction and heat. This excess heat can cause the tire to wear out faster and can ultimately lead to tire failure. A tire with insufficient air is also more prone to being deformed under the weight of the vehicle, impairing the driver's control and the vehicle's handling characteristics, potentially leading to accidents.
Furthermore, under inflated tires can negatively affect fuel economy because a tire with low pressure requires more energy to move and maintain speed. For safety and efficiency, it is important to maintain tires at the correct inflation level. Tire pressure should be checked regularly, especially before long trips or when carrying extra load. Manufacturers often specify the optimal tire pressure for cold tires, as pressure will naturally increase with temperature when the vehicle is in motion.
Tire pressure gauges are calibrated to read zero at atmospheric pressure and should read a positive value when the tire is inflated above atmospheric pressure. Maintaining correct tire pressure is not only critical for safety but also for the longevity of your tires and overall vehicle performance.
