To pump a spare tire, use the valve stem to fill it with air, just like you would with any other tire on your vehicle.
Step-by-Step Guide to Inflating Your Spare Tire
Whether you have a full-size spare or a compact spare, the process of inflating it remains essentially the same:
- Locate the Valve Stem: Identify the valve stem on your spare tire. This is where you connect the air pump or compressor. Even compact spares have valve stems.
- Remove the Valve Cap: Unscrew and remove the valve cap from the valve stem. Store it in a safe place so you don't lose it.
- Attach the Air Pump or Compressor: Connect the nozzle or chuck of your air pump or portable air compressor to the valve stem. Ensure a secure connection to prevent air leakage.
- Inflate to the Correct Pressure: Consult your vehicle's owner's manual or the sticker on the driver's side doorjamb for the recommended tire pressure (PSI). Inflate the spare tire to this pressure. It's best to use a tire pressure gauge to accurately monitor the pressure. Compact spares often require a higher PSI than standard tires, sometimes as high as 60 PSI, so always check the recommended pressure.
- Check the Pressure: Use a tire pressure gauge to verify that the tire has reached the correct pressure. Add or release air as needed to achieve the recommended PSI.
- Remove the Air Pump: Once the tire is properly inflated, disconnect the air pump or compressor.
- Replace the Valve Cap: Screw the valve cap back onto the valve stem to protect it from dirt and debris.
Important Considerations:
- Compact Spares: Compact spare tires are designed for temporary use only. Do not drive on them for extended periods or at high speeds. They are smaller and may handle differently than your regular tires. Get your regular tire repaired or replaced as soon as possible.
- Full-Size Spares: If you have a full-size spare, it's essentially the same as your other tires. However, it’s still wise to check its condition and inflation regularly.
- Safety: Always inflate tires in a safe location, away from traffic.
By following these steps, you can ensure your spare tire is properly inflated and ready for use in case of a flat.
