I do I put air in my tires, I tried to fill tires, but air was deflating instead of supplying??
No special way on these if you get the air chuck on the valve stem correctly the air should go into the tire, but the air compressor needs to be able to overcome the pressure already in the tire, if you are using one of those little 12 volt compressors it can take a long time to inflate a tire.
Sometimes you have to press really hard on the valve stem with the airchuck for it to seat properly. HTH. -Jim
