Airing Dualies

[Archive]

This is probably a well worn subject and I'm a little embarassed to ask, but what is the best way to air the training wheels?

I see a lot of extenders advertised and one or two that tie both tires together pressure wise. Do they pose a tire ballancing problem?

Thanks in advance for any advice and or pointers to previous threads.

John,we all learn by asking,don't feel bad. I use a truck style air chuck,it's metal about a foot long with two outlets at a 60 degree angle to the shaft. My pressure gauge is the same shape,you can either push or pull it onto the valve stem. Most truck stop air hoses have what you need for your dualys,just air up at one when you get fuel. I'd be leery of extensions or the like,because of the balance problem and the extra leverage they put on the valve stem when the tire's spining.

John, I have had 19. 5" Alcoas on my truck for two years now without any problems with airing them up or down. The inside rear wheels came with an extension that sticks thru the outside wheel. It will not cause a balancing problem as long as the valve stems sit 180 degrees from each other. Then again, I run internal balancing stuff in my tires, so it would correct any problems that I did have.

JSchooley, I've been running a set of chrome valve stem extenders for the past several months, like them a lot since I air my tires up and down depending on load a lot. A few days ago one of the OEM type rubber valve stems did fail and cause a flat on a inside duel. I suspect I damaged it on rock or limb. Replaced the leaking stem with a metal one like you would use in a tractor wheel. Had the other inside dual go flat a couple of weeks later, same deal. Replaced with the metal stem and don't expect to have anymore problems.

If you do go to some type extensions, I'd suggest changing to the metal stems if you drive offroad on in obstacle strewn areas. And do get the big truck type air gauge and air chuck as well.

Here's another vote for the metal stems, had em' put all the way around and on the spare. I tried the tube entensions that mount to the outside rime and they let go runnin' about 80 mph and pulled my inside valve stems out with em'. Stopped at a C. B. shop one day left my truck idlin' in the parking lot and heard a loud hissing sound which I discovered was another inside valve stem that spilt open for no apparent reason. That was when the metal stems went in and straight metal extensions were added to the inside rears. Now all valves are usable and dependable.

Last winter I had a valve extender hose, hold down bracket and rubber valve stem leave the rim causing the tire to go flat(inside dual).
The cause was the bracket came loose which made the whole thing like a sling shot. I lost the whole thing. Hope no one was behind me cause I did not know when it happened.
Agree that metal stems are the best way to go.

I had a set of the extenders for RVs sold by Camping World on my 3500. One of them came loose in the middle of 'Nowhere New Mexico' and ripped the valve stem out of an inside dually... . Not fun changing a tire in the middle of nowhere in the snow..... Anyway, I've since had the next length valve stems installed and make sure they are lined up with an outside wheel hole when mounted. I use one of the old style service station air chucks with the guage built in to measure and inflate my tires. Additionally, the Hadly Horn compressor/recover tank is an excellent source of air while on the road.

Thanks all for your inputs.

I do have the truck chuck with a good guage. Removing the valve caps and getting the chuck squarely on the valve with my bifocals has been my main problem. I can always get there but I was hoping for the instant panacea.

Your inputs are very helpful, if I decide to get extenders I definitely will get the metal valve stems.

Thanks again.
