TPMS - Don't like looks the rear inner value stem!

[PSchw]

I had the same. After installing the TPMS both of my rear inner tire would loose air. Of course the TPMS did let me know.

Before spending the $120 I want to me sure they'll fit:

The AI dual rear wheels are steel rim on the inner and aluminum rim on the outer. These DKL1SPAL work for that - correct?

The straight long one goes on the inner wheel (currently a rubber stem)l, with the rubber grommet going in the aluminum outer wheel and the inner stem is threaded through the grommet - for extra strength.

The 135deg one is a replacement stem for the outer rim - but is a bit unnecessary. My outer rim already has a metal stem, allowing me to screw a 135 deg extension onto it. This simply replaces the two-piece outer stem with a one-piece. Correct?

Titus - you are correct.

I have a 2016 Interstate Grand Tour Ext and believe the DL1SPAL is the one that fits my vehicle. I plan on ordering these and have the local tire shop (Gateway Tire) install these. I don't want to sound to dumb, but what is the proper alignment of the inner tire stems? They may know this, I just want to be able to tell them and also be able to visually see that they are installed correctly. I also plan to have all tire balanced, is this something most Interstate owners have done?

Thanks

The inner extension comes straight out thru one of the "windows in the outer wheel. There's a rubber stabilizer that fits in the window and the extension comes thru the hole in it. There's really no alignment required.

Besides balancing, you should also get the front end aligned w/ the van loaded as close as possible to the normal travel weight. Have the camber set as close to zero as the specs allow. This may require the special camber bolt that MB sells.

That's a new one on me! My Interstate doesn't have any kind of rubber stabilizers that fit the slot in the outer wheels— never did. Any idea where I could buy some?

Thanks appreciate the info.

They come with the DL1SPAL Dually Valve Kit. You can check with

yourtireshopsupply.com to see if they are available seperately. One thing to consider is that over the years Airstream used different wheels with different size/shape hand holes and the stabilizers are specific to the hole configuration.

They came w/ my DL1SPAL Chrome Dually Valve Kit.

Question how do I determine if I will need the special camber bolt? Is this something that can be determined before the shop does the alignment or is it only determinable as part of the alignment? Just wondering if I should order before I take it in.

Thanks

Will be determined during the alignment. He could align mine within spec w/o the special bolt but couldn't get it close to the "zero" side of the spec. Since I wasn't at a MB dealer, I had to leave it at that. Haven't put enuf miles on the tires to see if it was enuf to eliminate the excessive wear on the outside rib.

If you have yours done at a MB dealer, you could check to see if they have them in stock. I think they run about $8.00 ea.

My dealer charged me $15 for a pair used during my alignment.
