Dually valve stem…
Hi FTE! Been reading this forum for a few days. I’ve got a new To me 2020 F350 dually. Purchased the truck a few days ago (my first Ford) and it’s great besides the tire air pressure.
I have owned several dually before snd never really had an air pressure problem.
5 days into ownership my ford app alerts me that my tires are losing air. When I got the truck I was excited it had a tpms. I check my air pretty regularly because I tow often. I go to check the truck and it shows I’ve lost 12 psi in the fronts and 8 psi on the rear. Both front snd back consistently fronts started at 79 the day I got it (pretty high for fronts) now 67 on both. The rears started at 68 and now 62 (all four).
I’ve read almost all the pages on my search here in regards to this issue. Threads were older, 2018 or so. So I am wondering if there has been a solution. As far as I know there isn’t a TSB on it.
I’ve read rubber stems. Some say it works and some says it doesn’t. Some has said to buy new rims (Alcoa 19.5) but I like the way the stock wheels look compared to the 19.5. Looking for solutions!
also if there is a cord dealership in LOs Angeles that actually knows dually, please recommend. Bought my truck 100 miles away from me.

You might try Tom's Truck Center at 13443 Freeway Dr in Santa Fe Springs or 909 N. Grand Avenue in Santa Ana. Their Santa Fe Springs location is where Carmenita Ford Trucks was. Both locations are adjacent to the Santa Ana Freeway, I-5.

From a mechanical perspective, the mechanics required to get a good seal would be;
1 A polished hole surface free of any corrosion ( polish the hole clean and free)
2 some type of rubber safe lubricant (I would use Dow molycote on the rubber valvestem installation)
3 a rubber valvestem pushed in with the molykote lubricant applied around the sealing area
That's the steps that I would take if I were having an issue. I know it would be a huge pita to do all that because it would require bare rims, but it is what it is.

If its under 36k miles call a dealer and tell them the issue. They just tightened my valve stems and it worked I think, was loosing about 1-2lbs a week on a rim. Otherwise they need to clean the hole and install rubber stems.
Annoying to loose 20 mins of a work week to find someone to top off my tires.
I assume this is the aluminum wheels causing your problems.

They are a pain even putting on aftermarket valve stem’s doesn’t work for long. I have 2 duallys one with factory rims and have dealt with that for 3 years. The other I have aftermarket rims on not one single problem with air pressure.

If its all 6 you are lucky, its just loose valve stems.
I would explain the situation to a Ford dealer and see if you can get in and out.
Maybe pay for a tire rotation or something so it all makes sense.

True. Didn't think about that. The truck came with mis matched tires so there definitely was a tire change at some point ( which I thought was weird, truck only has 18K miles). I will see if that's the case.

Had the same issue Ford changed mine 5 times under warranty....now that warranty is over the tire shop replaced with rubber valves....the stock valves and aluminum wheels don't get along corrosion...and if bad enough will pit the wheels where the valve seat is and if bad enough no valve will work to seal...New wheels needed....the Dealership I deal with there was about 60 of us with the problem of the 60...9 customers had to get new wheels..
