Healthy tires are a critical feature of a safe car. One of the easiest ways to prevent a vehicular accident is to maintain optimal pressure in your tires. Secure stability, braking, and cornering all depend on proper tire pressure. Tire failure, which is usually the result of underinflated tires, can result in serious accidents. Fuel efficiency and tire longevity also depend on tire pressure.
While most cars now include a tire-pressure monitoring system (TPMS), these devices only indicate very low pressure, not whether or not pressure is most advantageous. In fact, more than 40 percent of vehicles with a TPMS have tires that are not properly inflated. In order to maintain optimum pressure, check your tires regularly, especially when the weather turns cold.
