DIY: How to Fill Your Car's Tires with Air
Your car's tires undergo plenty of stress during your daily commute, which causes them to regularly lose air. When you notice one of your tires looks low, it might be time to inflate it. Fully inflated tires not only promote a safe ride, but they also can improve your vehicle's gas mileage and performance. Here are some simple steps for filling a car tire with air.
What you'll need:
Step 1: Remove the Valve Stem Cap
Unscrew the cap covering the valve stem on your tire. The valve cap is small and should be placed in a secure spot so it doesn't get lost.
Step 2: Check the Tire Air Pressure
Use your tire gauge to check tire pressure. A gauge will give you the approximate air pressure in your tire. If it's lower than the maximum tire pressure rating on the sidewall, you should inflate your car's tire.
Step 3: Insert the Air Pump's Hose into the Valve
You might hear a hissing sound until the hose's head is fully aligned with the valve. Once the head is properly connected to the valve, the sound should stop.
Step 4: Inflate the Tire
If you're using a manual air pump, begin to pump the tire with air. Air compressors or automated gas station pumps usually let air flow out of the hose once they're turned on. Make sure to fill the tire in small bursts so you don't overfill the tire. Overinflating your tires can cause uneven tread wear or blowout in worst cases.
Step 5: Check Tire Pressure Again as You Go
As the tire is inflating, check the tire pressure until you reach the maximum rating. If you go over the recommended tire pressure, release air by pressing the center pin in the valve with a flathead screwdriver or your fingernail.
Step 6: Screw the Cap Back on the Valve
When you have the right amount of air in your tire, put the cap back on the valve. It's important the valve is covered so air doesn't seep out of your tire at a faster rate than usual.
