Dually Air Valve Extender

[Glamper1]

Big O orders the part

They worked on and ruined wrong valve and left the other one as is

and shows me the air hose fitting that I can never find at gas stations to reach the one
I came to Big O for.

What a mess.


I told them I'll come back Friday so they can undo this job.

Does this look right to anybody? Especially how the clammed down on finished polished aluminum?

Looks like a mess to me.

You should get these:
DL1SPAL Chrome Dually Valve Kit

They look like this installed on my Interstate with TPMS sensors installed.

Good Luck,

That IS a mess. And look how that bolt is in there trying to support the valve! I hope they didn't drill a hole in the wheel to take in that bolt.
Didn't anyone warn you never to use BigO Tires? They have a very bad reputation around here.

[Glamper1]

Thanks guys

I was nice but inside I freaked out.
Hopefully no damage to rims otherwise I will insist that they replace them.
Such a hack job
and...on wrong valves.
Unbelievable.

That is Youuugly.

I haven't gone to Big O since around 1997 when they effed up a brake job on my truck. They ended up refunding me more than the cost of the work.

I used these on my outer duals:
Amazon.com: Wheel Masters 8029180 180 Degree Valve Extender - Pack of 2: Automotive

I used these on my inner duals:
Amazon.com: Wheel Masters 80293 3" Straight Valve Extender - Pack of 2: Automotive

And I used this on my spare:

Thank you protagonist !
That's exactly what I assumed
I'd get.

Easy to put on yourself?

Easy enough if you do it with the wheels off the van. Harder with the wheels on the van unless you have really small hands with very nimble fingers.

The one for the spare requires that you drill one hole to mount the end of the extension on the rear bumper or hitch receiver. But being able to check the pressure in the spare without crawling underneath is worth it.

Next time, go to a truck tire shop. There's a difference. They've got the right equipment. They're experienced with dualies.

Just because they say, "We work on all makes and models," doesn't mean they can do the job right the first time.

These are the ones I put on my AI. The valve stems were installed at the local Discount Tire with my gentle supervision. They did a nice job at a very reasonable price. The TPMS I installed myself.

Because you have to remove the valve cores before putting on the extensions?

The inside rear wheels use a rubber valve stem with a plastic extension that is difficult to get to. I put a metal extension on that stem without securing it to the wheel. Both of those plastic extensions failed costing me two damaged flat tires. I bought the new extensions from a place that deals mostly with semi's. They always use metal valve stems for their extra rigidity. When I installed the TPMS system, I ended up with metal valve stems on the inner wheels. You can see the extensions I used in this thread:

Metal vs rubber or plastic extended valve stems have been discussed several times around here. The vast consensus is never use plastic or rubber valve stem extensions especially if you are going to use pass through external TPMS sensors. The slight added weight of the sensor will cause the plastic and rubber extension to vibrate excessively and even worse — break. When they break the first corollary to Murphy's Law immediately comes into effect. Remember too the inner rear wheels are steel and the outer ones aluminum, so you have to have metal valve stem extensions that are specific for the different metals. The Dl1spal]DL1SPAL Chrome Dually Valve Kit set has the right materials for both the inner and outer wheels.

From the posts on these forums, it also appears there is a preference for pass through external TPMS sensors. You do not have to dismount the tires to install them or change their batteries and the internally mounted sensors often have their signals blocked by the wheel itself. I even put external TPMS sensors on the wheels of my tow dolly and the rear wheels of the toad itself. I did have to use the long range antenna on the readout to reach the rear wheels on the toad.

The right rear outer wheel does not always read on my system. That is one of those wheels that has an inner band mounted sensor and is the farthest away from my display unit. Dill sells an amplifier to fix this issue. It just came the other day and I will be installing it this week.

I too used the Dually valves and I used them as well on my prior Sprinter based B+ RV. I had mine installed by Les Schwab Tires and having explained that I wanted the inners properly lined up with the wheel grommets they did an impecable job for around 90 bucks. While I was at it I had them pull the front wheels and balance them as the 4 rears were all out of balance. (fronts were out too). I then installed the TST TPMS system and am very happy with the whole deal. I like the TST product because of the user changable batteries.

I using the TST too works good but had problems with the seal on the battery door.
Did you balanced your wheels with or without the pass trough sensors?

My wheels were balanced without the sensors because I had not purchased the TST system yet. I also used the standard sensors and not the pass thru's because I take mine off between trips to conserve the batteries. Going on two years now with original batteries.

[PSchw]

I got the pass through and I leave am on now I am starting also to have to change batteries. I got about 50k miles with them.
Do you experience pressure increase when driving? If I put it up on 61 psi after a 1/2 hour I am at about 72 psi more extreme in the winter now I set them cold on 55 psi and end up around 62 to 65 psi on all wheels.
I was wondering about the extra weight on the valve special with the large pass troughs.

All tires heat up slightly as you drive, due to constant flexing of the sidewalls among other things. This heat causes an increase in tire pressure. As long as the increased pressure is less than the maximum pressure the tire will hold then everything is copacetic.
