Thanks PatJ... exactly what I was looking for... I was all over that site too. and googled the snot out of it. that is the RV site.. I have not been able to find the LT or P charts.
JIMNLIN... that was what I was trying to find out about running E tires under load at lower pressures. the pressure build up test should tell me if I am running too hot. I dont need 80lbs in these tires with my load. from what I gather proper inflation will be different for me compared to someone weighing 4,000 lbs heavier.
Dodgeboy... that is what I think too and I don't need 80psi.. I did make sure they gave me the proper stems. I just wanted a bit more pressure then my P tires and the stiffer sidewall of the E..
thanks all.

Someone needs to post a link that shows you can’t put E load range tires on rims that had P metric tire. There is no difference between the rims guys call any tire shop you want and they are going to tell you all you need to do to upgrade to E’s is replace the valve stems from the rubber ones to the metal ones. If they tell you anything different then they are tiring to sell you rims to get into your pocket book.

So, if I understand it correctly, there are special valve stems for trailer wheels and higher load rated tires. I know that there are metal ones, but I did not know that there was a difference in the rubber ones. I ask because I had my trailer ones replaced (load D) at a local tire shop last year. They were cracked and I know the place does not sell anything related to trailers.
our trailer wheels don't require a special stem. I use high pressure rubber (100 psi) for over 50 psi tires just like our 2500/3500 trucks come from the factory with. Many members on this web use the metal clampins or the outside of the stem is threaded for a nut type but isn't necessary. Any stem can leak as they all have a rubber seal to the wheel and the same valve core. I personally don't use a metal stem on any of my trailer wheels, even the RV.

As you can see the rubber valve stems will not work at 80 PSI

Not many people move up to higher class tires and typically stick with
what their truck came with.
The wheel spec is usually stamped on the back side or inside.
Wheels do have weight carrying and PSI ratings, just like tires.
Here are a few links for after market wheels and note that they have
PSI ratings, along with weight ratings.
Tires, valve stems, etc all come in different classes. From Passenger
"P", to Light Truck "LT", to commercial. All in ever increasing weight
carrying capacity and PSI. Wheels are also rated according to their
weight carrying capacity, and ever increasing PSI goes with it.
Curious that you understand tires & valve stems with these metrics, but not
wheels... They are in the same food chain classes. Or are you saying
"can't" as in that the bead design is the same between'm? That is true,
but their PSI ratings are different. Haven't seen a failure in decades,
but the ones I've seen failed by cracking along the bead area when
"P" class wheels had "LT" class tires mounted on them and used at
the tires maximum ratings (higher PSI & Load).

Is that what you are talking about? click on my link go to the bottom of the page and you will find them, the point is this is a “special” valve not the standard rubber valve no myth just fact.
most wheels are pressure rated. Simply changing a stem will not increase a 65 psi rate wheel to a higher psi (example). Some aluminum alloy wheels (16"/17.5"/19.5"/22.5" example)have that ability but that is the aluminum wheel manufactors rating as the alloy meet psi specs to do so. See NHTSA web for input on wheel pressure/capacity. Our 2500/3500 trucks come from the factory high pressure rubber that are 100 psi rated. See 600 series OEM high pressure rubber stems at the bottom of the page 100 psi rubber stems. these are the only stems I use on trucks or any of my trailers with P or E tires.
