1. Check Tyre Pressure: First, check the recommended tyre pressure for your car. You can find this in your vehicle's owner's manual or on a sticker typically located on the driver's side door jamb or inside the glove compartment. The recommended pressure is usually between 30 and 35 PSI.
2. Purchase or Find an Air Pump: You will need an air compressor to inflate the tyre. Many petrol stations have self-service air compressors for a small fee. Alternatively, you can purchase your own portable air compressor.
3. Remove the Valve Cap: Find the valve stem on your tyre and unscrew the cap.
4. Attach the Air Pump: Attach the air pump to the tyre's valve stem. Ensure it is securely in place to prevent any air from escaping.
5. Inflate the Tyre: Turn on the air compressor to begin inflating the tyre. Pay close attention to the pressure gauge to ensure you don't over-inflate the tyre.
6. Check Tyre Pressure: Occasionally stop inflating to check the tyre pressure. You can do this with the gauge on the air compressor or with a separate tyre pressure gauge.
7. Repeat for Other Tyres: Once the first tyre is inflated to the recommended PSI, repeat the process with the other tyres.
8. Replace the Valve Cap: After each tyre has been inflated, make sure to replace the valve cap. This prevents any debris from getting in the tyre and any slight air leaks.
Tip: Always check your tyre pressure when the tyres are "cold" (i.e., hasn’t been driven for a few hours) because driving warms up the tyres and increases the pressure. If you have to drive to find an air pump, it's better to slightly under inflate the tyres, then check and adjust them again when the tyres are cold. Also, remember to check your spare tyre. Don't try to reduce the pressure of over-inflated tyre by pressing the central spindle in the valve, it may damage the valve. Instead use a tyre pressure gauge device which has a pressure release button.
