Good news, it is located directly behind the outside tire's valve stem making it easy to find from the outside of the truck. The not so good news is that they are quite far back making them hard to get air or even a tire gauge to it. The dual wheel valve stem configuration is that the outer tire valve stem points away or toward the truck while the inner one points outward. I will need a tire gauge that has a dual end on it with one pointing the opposite direction from the straight end.

I then went on-line to see if this was some sort of issue I never heard of. Seems from what I read on the Ford Super Duty site that I probably have the wrong valve stems installed. This makes sense as the front tires are brand new and the valve stems were probably change out with the tires. I didn't know that there were different stems, low and high pressure. The low are good up to 65psi and are in most automobiles. I also found out that the tires should be inflated to the level recommended by the maker of the truck, Ford and not the maximum rated pressure on the tires. The pressures are found on the inside of the drivers door frame. There is a big difference between the Ford pressures and the tire max pressures.
All of the tires are rated at 110 psi and Ford recommends the front be 85 psi and the back be 75 psi. Big difference from the current 120 psi! So I have tires over inflated by as much as 60% and possibly with low pressure valve stems and I have one tire losing pressure quickly in front of the house. I can't drive the truck because the tire is too low and I don't know where to go that they have air. So Patty calls our insurance company where we have roadside assistance and has someone come out to tow the truck. Before the tow truck arrived, my neighbor Neal came over to see if he could help with his small air compressor. We thought maybe by blowing in some air through the valve it would seat. His air compressor only got up to about 80 psi but it was enough as the tire was now at 40 psi. The blow back seems to work as the valve seemed to seat.
The tow truck arrived and had an air supply and I decide to try and fill the leaking tire and see if that further fixes the valve problem and get the tire back to where it should be. However, the tow truck can't get the pressure past 70psi. I let the tow truck go and decide to go to a tire shop and get it checked. Went to Crown tire about 5 miles from here and they took me in quickly. I was right, the valves were the wrong size so I had them replaced on the 2 front tires.

After all of that with the tires, we still had time to keep our original plan to see a movie and have dinner at one of our favorite places. We decided to see the movie Ted at the theater in Atlantic Highlands mainly because on Tuesday it is only $7. A short walk form the theater is the restaurant Off the Deck located on the water facing Sandy Hook and the Manhattan skyline. We liked the movie but should have rented it on DVD. No need to see it on a big screen. Dinner was great. We sat at the outside bar and watched the ferry (SeaStreak) deliver passengers back from their work day in NYC.

All in all an educational and good day.
