Maintaining the correct tire pressure is crucial for several reasons. Incorrect tire pressure can lead to reduced fuel efficiency, decreased tire lifespan, and compromised handling and safety. It is important to understand the impacts of both over-inflation and under-inflation.
Impacts of Over-inflation
Over-inflated tires can be just as detrimental as under-inflated ones. When your tires are over-inflated, they become excessively rigid and can result in a harsh and uncomfortable ride. Moreover, over-inflated tires have a smaller contact patch with the road, which can lead to reduced traction and increased braking distances. Additionally, it can cause uneven tire wear, specifically in the center of the tread, leading to the need for premature tire replacement. It’s important to regularly check your tire pressure and ensure that it is within the recommended range.
Impacts of Under-inflation
Under-inflated tires are a common issue and can have serious consequences. When your tires are under-inflated, they are not able to properly support the weight of your vehicle, causing excessive flexing and heat buildup. This can lead to tire failure, such as blowouts or tread separation, which can be extremely dangerous, especially at high speeds. Under-inflated tires also have a larger contact patch with the road, resulting in increased rolling resistance and decreased fuel efficiency. Additionally, they can cause uneven tire wear, specifically on the edges of the tread.
Optimum Tire Pressure for Various Vehicles
The optimum tire pressure for your vehicle can vary depending on the make and model. To determine the correct tire pressure, you should refer to your vehicle’s owner manual, check the tire placard on the vehicle itself, or visit the manufacturer’s website for more information.

It represents the amount of force exerted by the air within the tire on a square inch of surface area. Most portable tire compressors will display the air pressure in PSI, as it is widely recognized and used in North America.
Understanding BAR
BAR is a metric unit of pressure and stands for “barometric pressure.” It is widely used in countries that utilize the metric system. One bar is equivalent to approximately 14.5 PSI. Some portable tire compressors may have the option to display the air pressure in BAR instead of PSI. If you are more familiar with the metric system, you may find it easier to understand and work with BAR as the unit of measurement.
Steps to Use a Portable Tire Compressor
Using a portable tire compressor is a straightforward process, but it’s important to follow the proper steps to ensure safe and effective inflation.
