They arrive today. I will let you know after the install. But I have heard from others on the Yahoo Interstate Group that used these exact same valves on the same wheel combination (Alcoa/Steel) and they said they worked. Also, I talked to the guy at Borg (YourTireShop.com) and he assured me that they will work with my wheels and that any aftermarket TPMS external sensor will work.

I had the dually installed valves this week, and am on a 350 mile trip. So far, no problem. They seem to work exactly as advertised. I will install my TST TPMS when I return. Worth every cent. Before, as you know, was not easy to check the rear tires. Now, it's just like the front except there are two extra to check.

Highly recommended.

Gerald,

Is it a problem having the tires removed on the Alcoa wheels? I think someone told me that for the rear wheel the polished side would be on the bottom for tire removal and that they could get scratched by some tire shops. When the Borg extender valves were put on, you had to remove the tires on the Alcoa wheels to install them. What is your experience?

Did the long stem from the inner steel wheel need to be bent to fit exactly through the Alcoa opening? Were there any surprises during the install?

I have thought about tire rotation when Borg extenders are used. I think I would just swap the front tires side to side and do the same side to side for the rears (swap Alcoa and swap steel). What is your plan for tire rotation when Alcoa wheels and Borg extenders are used?

By the way, Bill at Borg bought an Alcoa Sprinter wheel late last year just so he could manufacture the grommet that fits in the Alcoa opening. The Borg Alcoa Sprinter aluminum/steel valves just came on the market in January, 2013 (Borg has always had the steel/steel available). The nice thing about them is that they replace the valves on the rears including the inner steel wheel that I think does not have a metal valve. The Alcoa fronts are left alone since they have metal valves that are reachable. Seems to me to be perfect for a TPMS. The grommet stabilizes the long stem from the inner rear.

Let us know your TPMS experiences.

Barry

Barry,

The first time I had the local tire shop rotate the tires per the manual's recommendation, they dismounted the rear outers by placing one face side down to break the tire. It left scuff marks on the wheel which I did not discover until I got home. I went back the next day and they took responsibility for it. The installer just screwed up and knew better. They replaced the wheel at their cost with an identical replacement.

Now, I always remind them to turn it face up (as if shelling out $300 was not enough to remind them for the replacement), not down, to break the tires to be sure he remembers. Other than being sure they realize it, it is not a problem to break both rears and remount them to balance. If I remember correctly, the inners just swap sides, and the outers swap with the front.

The valve install required breaking down both the outer and inner wheel. A very slight bent on the inner wheel valve was needed to make it at the right angle for the opening on Alcoa outer wheel. No problems since the install at all.

I will follow the manufacturer's recommendation to rotate them. The valves are not an issue concerning rotation. These are really not extenders, rather, just longer valve stems for the inners, and curved ones for the outer so both valves are looking right at you, making checking the pressure much easier.

The TST system arrives Monday in time for a 5000 mile trip coming up later this month. The price does seems high, but well, there is no alternative if you want a TPMS system on a 3500 chassis that I know of.

During your TPMS research, did you come across any sensors that mount inside a la OEM vehicles use?

FYI, David G from Sprinter Parts Depot is looking into availability of the factory TPMS. I'll post what he comes up with.

RE: Mounting Polished Alcoa wheels

Many specialty wheel shops use a non-marking rim-clamp machine. Just call around to make sure they can mount the outside rear wheels without scratching.

There may not be a factory TPMS. According to my local Sprinter Dealer (MB of Baton Rouge) the Sprinter 2500 comes with TPMS. The Sprinter 3500 does not, because it meets two exception criteria of the Federal Motor Vehicle Safety Standards for tires: (1) It has a GVWR over 10,000 pounds; and (2) it has six wheels— TPMS is only required for vehicles with 4 tires on the ground.

However, there may be an aftermarket inside-mount TPMS. I haven't been able to find one, but that doesn't mean there isn't one.

I also looked in original MB once. Not available for 3500. I picked aftermarket sensor and find them very useful. I am still not having them in all 6 wheels but on 4 plus the spare. The inside rear did not work for either plastic extension or plastic valve. The weight of the pass trough sensor did cause them to leak air which the system reported correctly.
I love the pass trough as I can fill without removing the sensor. The front of the rear wheels need a special extension to do so or a different valve as explained early .
I love this forum lots of good informations.
Thanks
Peter

Perhaps you can compare the pics of mine to yours and determine which slot it came out of? You can see the wire he pulled out of the connector tucked back and wrapped in electrical tape.
I'm embarrassed it took me this long, but I finally got this done and it worked perfectly. Here is the stock configuration. I've shown which wire needs to be removed to prevent the step from retracting with the engine running.

Thanks again for the help Russ!

Oh, and for anyone else thinking of performing this mod, use a small jeweler's screwdriver to release the pin as pictured:

That's funny. I used that exact tool and thought about taking a picture but forgot.
