Why is Tire Pressure Important?

Even though most of us have a busy lifestyle that doesn't leave much time for doing maintenance on our cars, it doesn't take much time to check tire pressure, and doing so can actually save money and might help to avoid a breakdown.
Under-inflated tires will exhibit an uneven wear pattern that reduces the lifespan of the tire. It also makes them spin less efficiently, making the engine work harder to accelerate. This translates into wasted gallons of gas each year. Tires low on air also become more susceptible to blowouts.
