Filling tires with air is one of the easiest DIY maintenance tasks for your car, and it’s also one of the most important, especially during the winter. Cold air reduces your tire pressure, which makes your tires have worse traction, so they’ll slip more easily in wet and icy conditions. Follow these easy steps to filling your tires with air.
First, check your owner’s manual to determine what the proper PSI for your car’s tires is. Then use a pressure gauge to find out the pressure in each of your four tires. Locate the valve stem in the rim of the wheel, take off the cap, and push the tip off the gauge into the stem. If the number it reads is lower than your suggested PSI, add air to the tire.
Many gas stations have a spot where you can fill your tires with air if you don’t feel like buying your own automatic or manual air pump. Just make sure you bring lots of quarters. Park near the air pump and take the caps off all the valve stems, but don’t lose them!
Then, just like checking the pressure with the gauge, push the tip of the hose into the valve stem and fill the tire with air, stopping periodically to read the pressure again. Once your tire is at the appropriate pressure, replace the valve stem cap. Repeat with the other tires as needed.
