Now that winter is over and spring has officially started, it’s time to check your tires’ air levels. Cold weather makes tire pressure fluctuate, so get yourself a good pressure gauge if you don’t have one, and follow these steps on how to put air in tires.
First, find the valve stem on the inside of the tire, uncap it, and put the end of your pressure gauge into the stem to check the pressure. If the pressure is lower than the psi suggested in your owner’s manual, you need to add air.
The easiest way to do this is to go to a gas station. Most have consoles where you can put air in your tires for a quarter. Park close to the air pump. Just like when you checked the pressure, unscrew the cap on the valve stem.
Start the machine and place the tip of the air pump into the valve stem and let the air flow in. If you hear a loud rush of air, it probably isn’t secured properly, so wiggle it around. Check the pressure as you go. When you’re done, recap the valve stems and repeat as needed on the other tires.
