How to Fill Tires with Air

Filling a tire with air

Maintaining the correct car tire pressure is crucial for the safety, performance, and fuel efficiency of your vehicle on the Knoxville and Indianola roads. Below, we’ll walk you through the steps on how to fill your car’s tires with air and provide insights into the importance of proper car tire pressure as well as answering the question “how much air should I put in my tires?”



Why Maintaining Proper Car Tire Pressure Matters

Before we get into how to fill tires with air, let’s understand why it’s essential to keep the proper car tire pressure:

  1. Safety: Adequate tire pressure ensures optimal traction and handling, reducing the risk of accidents, especially during adverse road conditions.
  2. Fuel Efficiency: Underinflated tires can cause increased rolling resistance, leading to reduced fuel efficiency. Properly inflated tires can help save money on gas.
  3. Tire Longevity: Overinflated or underinflated tires wear unevenly, decreasing their lifespan. Proper tire pressure promotes even tread wear, extending tire longevity.
  4. Handling and Performance: Correct tire pressure enhances your car’s handling and overall performance, making it more responsive on the road.

How Much Air Should I Put in My Tires?

Refer to your owner’s manual, or the placard located on the driver’s side door jamb, or inside the glove compartment for the recommended tire pressure. It’s usually expressed in PSI (pounds per square inch) and reflects how much air yo should put in your tires. Then, you can continue on with the steps for how to fill tires with air:

Gather the Necessary Tools:

  • Tire pressure gauge
  • Air compressor (available at most gas stations or for home use)

Park Your Car:

Park your vehicle on a level surface and engage the parking brake.

Remove the Valve Cap:

Unscrew the valve cap from the tire’s valve stem and place it in a safe spot.

Use the Tire Pressure Gauge:

Attach the tire pressure gauge to the valve stem by pressing it firmly onto the stem until you hear a slight hissing sound. This means the gauge is properly connected.

Check the Current Pressure:

The gauge will display the current tire pressure. Compare it to the recommended pressure from your owner’s manual or vehicle placard.

Add Air:

If the tire pressure is too low, connect the air compressor to the valve stem. Press the air compressor’s trigger and fill the tire with air in short bursts, checking the pressure periodically with the gauge.

Check Pressure Again:

Stop periodically to check the tire pressure using the gauge. Avoid over-inflating by adding air in small increments.

Replace the Valve Cap:

Once the tire reaches the recommended pressure, remove the gauge and quickly replace the valve cap to prevent dust and debris from entering the valve stem.

Repeat for All Tires:

Repeat this process for all four tires, including the spare if applicable.


After filling all tires, double-check the pressure to ensure it matches the recommended levels.

Record the Pressure:

Consider keeping a record of your tire pressures, so you can easily track any gradual pressure loss over time.
