Several key reasons underlie the importance of maintaining proper tire pressure. First, under-inflated tires increase rolling resistance, leading to decreased fuel efficiency. Second, over-inflated tires can cause a harsher ride and might lead to uneven tire wear. Third, the right tire pressure enhances traction, especially in adverse conditions such as rain or snow.

Tire pressure is determined by the volume of air within the tire. If the pressure is too low (under-inflation), the tire becomes soft, resulting in less surface area touching the road. Conversely, if the pressure is too high (over-inflation), the tire might have too much air, reducing its contact with the road and increasing the likelihood of a blowout.

The mechanisms involved include heat generation due to friction between the tires and the road surface. Under-inflated tires create more surface area in contact, generating additional heat due to excessive flexing. Over-inflated tires, however, can become rigid and less flexible, which can be dangerous at high speeds or when cornering sharply.

Specific conditions that contribute to improper tire pressure include temperature fluctuations and extended periods without checking tire pressure. For instance, colder weather can decrease tire pressure by 1 PSI for every 10 degrees Fahrenheit drop in temperature.
