Changing Valve Stems on Passenger Cars

  1. Preparation: Park your car on a flat surface. Loosen the lug nuts on the wheel.
  2. Lift the Car: Use the jack to lift the car and secure it with jack stands.
  3. Remove the Wheel: Take off the lug nuts and remove the wheel.
  4. Deflate the Tire: Remove the valve cap and press the valve or remove the core to release air.
  5. Break the Bead: Use a tire bead breaker or your weight to separate the tire from the rim.
  6. Remove the Old Valve Stem: Use a tire stem puller/remover tool to pull out the old stem if it is a snap-in. Loosen nut to remove for clamp-in style stems.
  7. Install the New Valve Stem: Lubricate the new snap-in stem with soapy water. Pull it through the hole in the rim until it seats properly.
  8. Reinflate the Tire: Inflate the tire to the recommended pressure and check for leaks using soapy water.
  9. Reinstall the Wheel: Put the wheel back on, tighten the lug nuts, and lower the car.

Replacing Stems on Light Trucks and SUVs

  2. Remove the Wheel: Take off the wheel using a lug wrench.
  3. Deflate the Tire: Release all the air from the tire.
  4. Break the Bead: Use a tire bead breaker or another method to separate the tire from the rim.
  5. Remove the Old Valve Stem: Use a valve stem puller/remover tool to pull out the old stem if it is a snap-in. Loosen nut to remove for clamp-in style tire stems.
  6. Install the New Valve Stem: Lubricate with soapy water and pull the new stem through until it seats.
  7. Reinflate the Tire: Use an air compressor to inflate the tire and check for leaks.
  8. Reinstall the Wheel: Put the wheel back on and secure it with the lug nuts.
