Dual Tire Inflators

[CJames]

I have dual tires on my Class C.
There is one vavle stem.
Inflates both tires at once.
If I get a flat wont both tires go flat or is there a valve inside that prevents this?

Seems to me the purpose of tying them together would be to ensure tire pressures are the same, so a valve in the line other than the fill valve would defeat the purpose.

Personally, I would bring the rig in and have a tire shop replace the valve steams with traditional individual valves while you are at it have the tires re balanced. As TX_Arvee said I think it is to keep the pressures the same. Which I suspect will help protect you from a shredded tire (theoretically at least). By having one tire at a lower pressure you risk increasing your tire temperature which leads to shredded tires. However, the risk of losing control if you lost both tires would scare me, at hwy speeds.

Does it appear to be a factory item?

As far as I can tell it came that way.
There is no tire stem on the outside rim.
The valve sticks out betwen the rims.Both tires are filled from the hub.

Try google - when I was researching valve stem solutions, I ran across at least one product like yours. As I recall, I think it said it would equalize pressure, but would not allow total loss of air in the event of a blowout on one of the linked tires. If you can figure out what brand you have, you may be able to verify whether you have a similar setup...

By the way, I ended up buying a set of Dually Valves from www.sixrobblees.com. Other than having to modify my wheel simulators a bit, I like 'em so far. Very easy to use.

Hummmm?
So if you have a flat, how do you change the tire? I could handle one tire at a time but I do not see myself being able to both rims simultaneously. There must be a way to connect them once you place the second rim on. I would hate to do that in the rain.

There must be a check valve on each line similarly to the ones on the propane lines that everyone seems to struggles with.

I hope so.
I'm going to get someone that knows to look at it.
Maybe I have a really great thing or I need fixing quick.
I'll keep y'all posted.

WELLLLLLLLLLLLLLLLLLLLL.
Duuuuuuuuu.
It turns out I should look closer.
That was just a valve stem extension.
The other valve stem was hidden by dirt.
I pulled the hub cap off and there was valve number two.
Oppppps.
So I drove 360 miles without checking ether outside tire.
I feel so intelagent. I should be in Washingtoon.
