I am having difficulty getting more air pressure into my dual tires over 70#. My air compressor says it has more than 100# in the tank. The tire has the factory installed valve extensions. does anyone else have the problem or a reasonable solution?

What is the SCFM rating of your air compressor? Generally speaking it should be over 2.0 to inflate large tires.

You didn't mention what make & model compressor. Many small or inexpensive compressors don't deliver much air at high pressures and it can take forever to add much air in the uper pressure ranges. It is unlikley there is a problem with the tire valves if you can get 70 pso in, so the problme is likely the compressor or the air chuck on the hose.

Do you have something else you can test your compressor on, something that can handle 85-100 psi?

please due check the chuck. i say this as a friend gave me a nice large type chuck and when i went to use it, i discovered the valve had worn out. replaced the head with an old one i had and was back in business after having spent a considerable amount of time trying to look elsewhere for the problem.
