The inside duals' valve stems on my new F-450 are virtually impossible to access. I had to remove the outsides to screw on the tire pressure monitors. I've looked at several extenders but none have been exactly what is needed to solve the problem. Any ideas?

One of these extenders in the top row might work. Of course you must have solid metal valve stems mounted in the rims to use either a TMPS sending unit or an extender.

Buy some dually valve stems. Solid metal stems long enough to extend through the outer rim.

I have looked at a dozen or more different extenders. The problem is that the stock valve stems do not point at an opening in the outer wheel but point at a solid part of the outer wheel.

I am looking for someone who owns a 2011 f-450 King Ranch who has found a workable solution.

You can rotate the outer wheel/rim assembly, one stud at a time, to have one of the "hand holes" line up with the inner valve stem. I had the same problem on my old truck because some uneducated tire techs did not know how to properly remount the outer rim & tire.

Ray: I just bought (after a lot of research and reviews) the Tire Minder tpms. Nothing on this system about solid metal valve stems mounted in the rims being a requirement. I am now worried I missed something?

Dlovitt are you using a truck pressure gauge? I have a good gauge I use for all my tires but had to switch to the remote gauge on a flex line to do my f350 duals.

I've got so many different tire gauges that I'm thing about opening an auto parts store!

The Valve stems should be 180 degrees from each other so you can get to both. Arctic Owl is correct in rotating one stud at a time till they are liined up with a hand hole. You try to get them at 180, which should be good.

Go to a commercial truck tire shop and they can custom bend stems for you.

Some owners have reported rubber stems flex enough, from the miniscule weight of the sensor, to allow very slow pressure loss. IMO, all load range E tires and heavier should use full-metal valve stems anyway, but that's just me. You may not have any problem using rubber stems, I would not be concerned unless your tires begin losing air pressure with the sensors installed. Keep metal stems in mind next time you buy tires.

Dually Valve These are the last you'll ever have to buy, they are one-piece and will require installation but are trouble free and a must IMO with TPMS.

This is similar if not identical to what I used on my 08 F450. I don't know about the '11 since the 19.5 wheels are no longer used. They are by no means an ideal solution. They can leak if not secured tightly. I did, however, use the extenders successfully for 2.5 years until I got rid of the truck. But at that time I wasn't using a TPMS. Not sure I would use the TPMS with a 6" valve extender. Lots of potential problems with that extra extension in the equation.

I am still amazed at Ford's lack of foresight putting that style wheel on a dually.
