Your signature doesn't state what type of RV you have so I am assuming that you must have a small Class C RV with small tires.

There is no way a competent tire shop would remove metal valve stems and install rubber ones even if the new ones were the high pressure stems that I use on my cargo trailer.

My Class A Winnie Warrior 22 had rubber valve stems on all wheels.

Well then, you have two options.

Return the tires and have them install metal stems at your cost OR return the Cross-Fire System for a refund.

Yeh Richard, that's the conclusion I have reluctantly reached. I was hoping some folks here would say they've been running crossfire with rubber stems for years without any problems but apparently that's not the case.

No matter what you decide, your coach was never suppose to have rubber stems. They need to be changed.

grafxman,
Even if they don't work on RV's. The maximum tire pressure for every tire is located on the sidewall of every tire. Any tire installer know that. If the TP said 110 lbs or anywhere on either side of that number they needed metal stems. That's a given if you know what you are doing. That's the point. They don't know what they are doing and put you and your family in danger.

The reason why rubber stems are NOT used with TP over 65 is because the rubber end which is holding the stem in place in the rim might blow out. Metal stems are bolted into the hole of the rim. They can't blow out.

On high pressure tires (most anything over 50 PSI) metal valve stems are specified or so I thought... I could be wrong.. Dealer messed up and went cheap on you.

Have him install Duly Stems as a compenastion (Stems alone are about a hundred bucks)

Well, I must say I've certainly learned a lot here as I always do in this forum. I went to the service station today and talked to the manager. I asked him how much they would charge to install metal stems. He said they should have already installed high pressure metal stems because he knew the tires were meant for a motor home. So I said that if they're metal stems then why can I wiggle them a bit. He then went to the back and brought one out. These are what should be on your tires he said. It actually does have a brass stem however the part that goes through the rim is a very hard, tough rubber. He said those stems are designed for high pressure. I checked the wheels and that is what's been installed. I think I'll try to contact Crossfire and see what they say about them.

There is the question of , do you want to run the valve at 100% of it's rated pressure or have metal valves installed and run them at 50% of their rated pressure.
More info here.

The link that Skip426 posted is a great explanation of valve stems.

What they installed are the same identical valve stems I have on my 16 inch tandem trailer wheels. I inflate them to 80 lbs max.

You need to figure out what size wheels you have, what max psi you can have in each tire.

To me if your RV wheels are 16 inches or lower then these are probably OK but if you have 19 inch wheels or higher metal stems are required.

At this point I'm awaiting a reply from Dual Dynamics, the Crossfire manufacturer.

Wheel size is 16, Michelin tires rated at 80 psi which is what I inflate them to. I've been running 2 Michelins on the front at 80 psi for 3 years without any problems. At this point I'm just awaiting a reply from the manufacturer, Dual Dynamics.

The pressure on the sidewall of a truck size tire is the minimum required to support the maximum weight rating of the tire. It is Not the maximum cold pressure the tire should ever have.

Quote:
From page 2 of the 06/07 Michelin RV Tire Guide: "If you look at the tire's sidewall, you'll see the maximum load capacity allowed for the size tire and load rating, and the minimum cold air inflation needed to carry the maximum load."
This is confusing since on car tires it is the maximum cold pressure the tire should ever have

Don't know about you, but it were me, I'd have medal stems installed, if nothing more than peace of mind.
