How to inflate car tyres

Posted On 27 Jan 2025

Inflating car tyres is a straightforward process, but it's important to do it correctly to ensure safety and optimal vehicle performance. Here’s a step-by-step guide:

What You Need:

  1. Tyre pressure gauge (digital or manual)
  2. Air compressor (available at petrol stations or for personal use)
  3. Vehicle's recommended tyre pressure (found in the owner’s manual, inside the petrol cap or on the driver’s side door frame sticker)

Steps to Inflate Your tyres:

  1. Check Recommended Tyre Pressure:

    • Locate the tyre pressure information, usually shown in PSI (pounds per square inch). Do'nt rely on the PSI rating written on the tyre itself; this is the maximum pressure, not the recommended level.
  2. Inspect Tyres:

    • Check the tyres for visible damage or excessive wear.
    • Ensure that they are cool before checking the pressure (we'd recommend waiting at least 3 hours after driving).
  3. Measure Current Tyre Pressure:

    • Remove the valve cap from the tyre.
    • Press the tyre pressure gauge firmly onto the valve stem and lock into place if needed
    • Note the reading and compare it to the recommended pressure.
  4. Inflate the tyre:

    • Connect the air hose to the valve stem.
    • Turn on the air compressor and let the air flow into the tyre.
    • Periodically stop and check the pressure with your gauge to avoid overinflation.
  5. Adjust the Pressure:

    • If you overinflate, use the pressure release button (if your gauge has one) or gently press the valve stem pin to release air.
    • Continue adjusting until the tyre reaches the recommended PSI.
  6. Replace Valve Caps:

    • Securely screw the valve caps back on, to protect the valves from dirt and debris.

Tips:

  • All tyres, Including Spare: Check all four tyres and the spare (if applicable) to ensure they are properly inflated.
  • Seasonal Adjustments: Tyre pressure may fluctuate with temperature changes. Check more frequently during cold weather.
  • Invest in a Portable Air Compressor: If you drive often, having a portable air compressor can save time and money.

Warnings:

  • Do not exceed the maximum PSI rating of the tyre.
  • Driving on overinflated or underinflated tyres can affect handling, reduce fuel efficiency, and lead to uneven wear or blowouts.
