Importance of Tire Pressure

Importance of Tire Pressure


Keeping your tires properly inflated has many benefits. Your tires will wear evenly, which prolongs their life and can improve your vehicle’s fuel economy. When correctly inflated, your tires can perform at their best which means better handling, dependable traction and a more comfortable ride for you.

Importance of Tire Pressure

A Few Things to Keep in Mind:

  • You should always set your tires to the pressure specified in your vehicle’s owner manual or tire information placard.
  • Always check and adjust your tire pressure first thing in the morning before driving on them.
  • Temperature differences affect your tire pressure. Cold, winter weather may cause your pressure to drop while warm, summer weather may cause your pressure to increase. Although you should check your tire pressure periodically as part of good vehicle maintenance, it is exceptionally important to check it when the season changes.
  • Always check your tires with a good quality tire pressure gauge. Many vehicles come equipped with a tire pressure monitoring system (TPMS). Generally, this system will alert you if your tires are losing air or are below the recommended pressure. You should never try to visually estimate your tires inflation pressure. We recommend keeping a tire pressure gauge in your glove compartment – even if you have a TPMS built into your vehicle. This will ensure you are getting a consistent reading each time rather than using multiple gauges at different gas or service stations. If you suspect your TPMS system is malfunctioning, we offer a TPMS service package designed to fix the faulty component.

Overinflation vs. Underinflation

Overinflated tires are rigid and stiff causing the tire’s contact patch (the amount of rubber that meets the road) to be reduced. That leads to a “harder” ride as well as uneven tread wear. The most common type of uneven tread wear due to overinflation is referred to as “center wear.” Exactly what it sounds like, the center of the tire will be smooth and worn down while there will be more tread on the sides of the tire. Due to the rigidity of an overinflated tire, it can be more easily damaged by everyday road hazards such as potholes and imperfections in the road.

Underinflated tires do not hold their shape and are flatter to the ground. Therefore, more of the tire comes in contact with the road, causing the shoulders of the tire to wear prematurely. That is referred to as “shoulder wear.” There will be a strip of normal tread down the center of the tire while the shoulders of the tire will be smooth and worn down. Underinflated tires are more flexible when they roll, leading to increased rolling resistance and therefore a decrease in fuel economy.
