Valve extender for inside tires


KodiakJack

Recommended Posts

Santa came down the chimney with a couple more sensors for our tire pressure monitoring system. I plan to install them for the inside rear tires on our DRW pickup. The pickup is in Arizona we're in central Washington so I can't quite visualize the best extender to get for our Chevy. So thought I'd ask what valve extender do you use for your duel wheel rig?

If I was going to do a dually pickup, I would have metal valve stems put in first, then do a Cross Fire system with the extra schrader valves in the lines. I messed with several "systems" made for dually pickups but never found one that wouldn't leak over time. Using what the pro's use is definitely worth while.

I agree on not using the screw on extenders. In the past I've had them work, and I've had them leak. No matter what you did with them. I know there are some people that use them without problems, but to me it is just a problem waiting to happen.

 

I like the long tire stems, and any shop can install them.

The aluminum wheels on my 3500 Silverado can only be rotated from left to right in the same position (i.e. LF to RF and LRO to RRO). The rear inners however can rotate with the spare. Since I rotate using the spare so that I to only have to lift one tire at a time I will need to put longer stems on all 3 of these wheels. Good point about using longer tire stems. Thanks for pointing it out.

PS Hate to sound like a salmon on the bank flopping around but I am now once again considering extenders. Maybe I'll give them a try.

PSS I have the TireMinder system.

The inherent problem with the Crossfire system is when using a TPMS, which is the OP's intent, the sensor will not tell when one of the dualls is flat or losing air on the monitor.

Post #15 of this topic. They have the hoses with an extra schrader valve for your TPMS system.

I agree, this is what it says: Q: If the Crossfire reads black, which one of the tires is low?

A: If you put an air gauge on the Crossfire when it is black, it will read the outside tire.

The TPMS is in effect a tire gauge, and will not read the inner dual per the Crossfire website.

You can order the Cross Fire system with the original schrader valve for adding air to the tires, AND an additional schrader valve on each line going to each individual tire that you place your TPMS sensor on.

This way you have the equalizing ability of the CrossFire, the isolation ability of the CrossFire, and the ability to read the tire and temp pressure of the tires from the cab. If a tire starts loosing air, the Crossfire will isolate that tire and your TPMS will tell you what tire is going down.

If you look at the CF-100-STV, you'll see that you can order these. The middle number is the air pressure that they are set at. Yo can order any air pressure range from 70-150psi ie.-CF-80-STV which I have.

If you give the guy a call from my first link, Ed Donnelly, can set you up with what you need, including a shorter hose for the 19.5 rims.

So, Jim, is it working well having the dual sensors?

 

I'd like an easy way to air up the inner dual. It would seem the crossfire would provide that, since it equalizes across both. So I only air at the input side of the crossfire and I'm done. Not that I air that often, but anything that makes dealing with duals easier is IMO a safety element - minor as it may be.

Well, now I'm confused_again. Does the Crossfire system tell you, at drivers seat, if one of the duals is loosing air? Again referencing the Crossfire FAQ page, stating if the indicator is black, only the outer dual pressure is measured. Or, Do you still need to install a TPMS??? I presently use a TST 507 TPMS system(flow-through), which extends the inner stem enough to add air without effort.

The crossfire won't tell you anything from the drivers seat. It only shows info on a walkaround. The TPMS WILL tell you at the drivers seat though.

 

The benefit of the CF to me would be 1) ease of airing the inner dual and outer at the same time. 2)....well I can't think of a two.....

There are no easy answers here. Fact is, the space is limited and the fixes are prone to failure. Works for some, not for others.

 

I've resigned myself to the fact that it's a pain in the ass. Chevy 3500 DRW..... To get to the rear wheel valves the plastic "hub cap" has to come off....

 

Answer: Battery powered drill with the necessary hardware to "zoom zoom" the plastic nuts. Off in less than a minute, do your thing.

 

No leaks.

 

No, it's not easy but it works and it's reliable.
