Valve stem question

I have the same problems with my rear tires and are contemplating to install the Cross Fire system (http://tinyurl.com/c2fe5k3).

Has anybody any experience with it and can report on it?

Had braided extensions on my former coach for 6 years. Never had a problem with them. They were restrained in spring clips so they did not move when the tire was spinning down the road. This was a factory installation. Current coach is solid all the way, although I never had a problem this is much neater.

I've had braided stainless steel flexible extensions on my Coachmen's inner duals and 135° solid extensions on the outer duals since 2008 with no leakage or any other problems. I installed a length of rubber fuel line over the braided hoses to add extra protection from road hazards.

..I tried every truck tire gauge I could find. RV dealer tried 'bout every one he had on the shelf, too. NONE would allow you to get to the valve on the outer dual on mine.

...Not to mention that even if I could get a gauge to reach it, NOTHING would allow me to attach an air hose to it (outer dual) for when it needs a shot of air. The ONLY option for the outers that allowed me to attach a gauge as well as an air chuck was a solid, 135 deg. extension. Sooo, thats what I use for them.

Solid, short extensions like that are not the problem. When installed correctly, they will not leak. The braided extensions are the ones that some folks have leaking problems with (although just as many folks like me have had no trouble with them).

Eventually I will probably replace the braided ones on the inners with a solid extension of some kind, quite possibly Dually valves. However, as long as the braided ones show no sign of wear or leaking....I'll stick with what I have. :)

I meant to also say, one of the best investmeents you can make is a good tire monitoring system.
If you blow a tire the damage it does to your motor home is alot more expensive than you'll pay for the montoring system.

The extentions are not reliable, they will leak sooner or later you can be sure of that. You need a 90 Degree truck tire gauge & throw all the extentions away.

Ok. I did not put them all the way on, once I heard air coming out I thought I had done something wrong so will give it another try tomorrow I guess. I have read a lot of the posts about the braided extensions...will keep a close eye on those and may eventually go another route. A lot to learn on these motor homes coming from a 19 ft. TT
Thank you for responding.

I have same setup on mine - braided extensions on inners, solid 135 deg. extensions on outers. I could not get to the valve stem on the outers any other way (no matter what type of gauge I used).

I put the 135 deg. extensions on the outers myself. Yes, a little air leaks out when you first put them on, but it should stop when you get them on good and tight. I don't recall more than just a little air leaking out when first installing those. If they're leaking no matter how tight you get them, something is definitely wrong.

You're probably going to get lots of posts here telling you that the braided extensions on the inners are a bad idea, and will leak. I've watched ours very closely, and after a year of ownership, have not experience ANY leakage from them at all. I am still leary of them, and will probably one day replace them with solid extensions of some kind. But, reality is that they have worked great so far for us.
