Knowing when your tire pressure is low isn’t always easy. So, how often should you check it and how do you fill them back up? Filling your tires with air is a simple maintenance task that will save you money and the headache of a blown tire.

When to Check Tire Pressure

When temperatures are cold, air pressure should be checked once a month. The air inside of a tire that is war will expand and cause an inaccurate reading so, in warm weather, park your car in a shaded area for a while before checking the pressure. Other times you should check tire pressure are if you run over something ahrp, if you strike a curb or other object hard, and if there is a drastic change in temperature.

How to Check Tire Pressure

  1. Purchase a tire gauge. They are quite small and can be easily fit into a console or glove box. Newer digital gauges are more accurate and precise than manual ones. Otherwise, you can use the gauge on the air hose at a gas station.
  2. Determine the correct pressure for your car. The optimal tire pressure will be listed in the owner’s manual or on a sticker in the driver’s side door jamb.
  3. Remove valve cap and press gauge into the open valve stem.
  4. Read the gauge, then fill with air.

How to Fill Tires Properly

After determining that your tire air pressure is low and testing it. Fit the air hose into the tires, fill them with air, and then check the gauge reading again. If the number is too low, continue to fill them more but if the number is too high you’ll have to let some air out. Replace all the valve caps and give each tire a light kick to make sure they feel good.
