When you have a car, you will want it to be in the best condition possible. This also includes having it operate at top performance levels. You should bring in the vehicle regularly to have the tires inspected. Between visits, you can inspect the tires yourself. In order to check tire pressure you will need a tire pressure gauge. They are usually about the size of a large pen, but they can come in other forms.
Look in the driver side doorjamb for a sticker that indicates the vehicle manufacturer’s tire specifications. There will also be specifications on the tire itself, which are the tire manufacturer’s specifications. However, the numbers for the specified tire pressure may be different between the two different specifications. The tire manufacturer’s specification indicates the maximum amount of pressure that the tire can safely hold. The vehicle manufacturer’s specifications indicate the recommended pressure for that specific vehicle. Follow the vehicle manufacturer’s specification on the sticker in the driver’s side doorjamb.
If you notice that a tire is low, you can fill it with air, or bring it in so we can inspect it for you. Make sure to remove the valve cap of each tire, align the gauge up to the valve, and press the gauge onto the valve with firm direct pressure and then release. You will see the measuring stick get pushed out of the other side of the gauge. Fill the tire with air, recheck the pressure, and then repeat as needed until the desired pressure is obtained, and remember to replace the valve cap.
Tire pressure is measured in PSI, or pounds per square inch. Pressure is a force distributed over surface area. Heat increases pressure, so you may find that your tires need more air, as it gets colder during the winter and less air, as it gets hotter during the summer. Some vehicles have a dashboard indicator light that will illuminate when the tire pressure needs to be checked or corrected. If a tire is losing air more often, bring it in because it may have a puncture or damage to the tire.
