Air is added to a tire using a pump (manual, electric, or compressed air) and connecting it to the tire's valve stem to inflate it to the recommended pressure.
Here's a step-by-step breakdown:
-
Gather Your Tools: You'll need a tire pressure gauge and an air pump. The pump can be manual (like a bicycle pump), electric (plug-in or battery-powered), or a compressed air source (often found at gas stations).
-
Check the Recommended Pressure: Locate the recommended tire pressure (PSI - pounds per square inch) for your tires. This information is typically found on a sticker inside the driver's side doorjamb or in your vehicle's owner's manual. Do not exceed the maximum pressure listed on the tire sidewall.
-
Prepare the Valve Stem: Locate the valve stem on your tire. Remove the valve cap by unscrewing it and set it aside in a safe place.
-
Connect the Pump: Attach the air pump's nozzle or chuck securely to the valve stem. Ensure a good seal to prevent air leakage. You may hear a slight hissing sound initially.
-
Inflate the Tire:
- For Manual Pumps: Begin pumping air into the tire. Regularly check the pressure using your tire pressure gauge.
- For Electric Pumps: Turn on the pump and let it inflate the tire. Many electric pumps have an automatic shut-off feature that stops when the desired pressure is reached. If yours doesn't, check the pressure frequently.
- For Compressed Air: Carefully add air in short bursts, checking the pressure gauge frequently. Gas station air pumps often deliver air very quickly, so overinflation is a common mistake.
-
Check the Pressure: Use your tire pressure gauge to confirm that the tire has reached the recommended PSI.
-
Adjust as Needed: If the tire is overinflated, use the pressure gauge (if it has a pressure release button) or gently depress the valve stem core to release air. Re-check the pressure. If the tire is underinflated, continue adding air until the correct pressure is reached.
-
Replace the Valve Cap: Once the correct pressure is achieved, remove the pump nozzle and replace the valve cap securely on the valve stem. This protects the valve stem from dirt and debris and helps prevent air leakage.
-
Repeat for Other Tires: Repeat this process for all tires, including the spare tire if applicable.
Important Considerations:
- Tire Pressure Fluctuations: Tire pressure decreases in cold weather and increases in hot weather. Check your tire pressure regularly, especially with changing seasons.
- Safety: Always inflate tires in a safe location away from traffic. Never inflate a tire beyond the maximum pressure listed on the tire sidewall, as this could cause it to burst.
- Professional Assistance: If you are unsure about inflating your tires, seek assistance from a qualified tire professional.
