Steps to loosening your car’s air valve caps 

What you will need: 

Spray lubricant (WD-40) 

2 snub-nosed pliers 

  1. Rotate your wheel/tire so the cap is upside down from your point of view. 
  2. Spray a small amount of lubricant onto the valve. 
  3. Tightly grasp the base of the valve stem with pliers. 
  4. Grasp the cap with your other set of pliers and twist until it becomes free. 
  5. Replace cap after filling tire with proper amount of air. 

It’s that simple. This process shouldn’t take longer than a few minutes, but if you still have trouble getting the cap off, try using more WD-40 and let it sit for a little bit before twisting again. Your tires require a lot of care. You should check your PSI levels regularly and get your tires rotated once every 5,000 miles or so.
