nothing other than mount them properly, I've taken my OEM TPMS out of stock wheels, had them switched over to aftermarket np. Quick and easy esp if you have tires removed already

 

There are TPMS 'rebuild' kits - depending on the age you might want to consider, especially if the rubber grommet looks suspect. New valve stems are a good idea regardless. About $3 each, you'll be out all of $12 if you do Amazon prime.


*If* your new set of wheels have TPMS sensors already, learn the new ones to your car. Not much more than setting air pressure at a certain PSI at each corner and grounding a connector under the dash with a paperclip. Car does the rest. See here:

My 04 G35x was identicle. Good for summer & winter wheels/tires setups.

 

Thanks

For reference, bought a set of 19in rims and tires (off a 2009), but 1 wheel does not have TPMS, so what I plan to do is remove my OEM 18in wheels, remove the tires, remove the TPMS, remove tires from 19in wheels, transfer TPMS from 18s to the 19s (scrap the ones they came with), reinstall tire on 19s and put them on the car.

The TPMS pretty much complicates the process in that each set of wheels first needs their tires removed then reinstalled (19in tires were coming off anyway for powder coating).

Just wanted to make sure I understand what needs to happen.

Thanks guys

 

You're fine. Same TPMS, different wheels.

Here's a related question: can the ECU support more than one set of TPMS? As I ride around on mis-matched wheels for the next few days, the TPMS warning light is not going away. I have the two OEM sensors in the front duckfeet, and the two new sensors in the rear Vossens.

I'm thinking I'm going to have to have my sensors re-registered each Spring and Fall, as I swap wheels for Winter. That sucks. I was hoping not to bother with that.

 

Nope, unfortunately the car only learns & knows 4 TMPS signatures at a time and doesn't retain old memory. So winter/summer sets require the relearn. Whats further aggravating is the car knows exactly which is the LF, LR, RF, and RR, yet only pops a dummy light on the dash when one or more tire needs attention. Could chalk it up as novelty, but the Dodge Charge SRT (and many others) will tell you on the dash what the tire pressure is on each corner.

 

I've been researching this "shorty" valve stem that Vossen ships with their 19" rims, and I think I found it. The Hawkshead T-Valve TPMS Adapter:

TPMS, TIRE PRESSURE MONITORING SYSTEMS - T-VALVES, VALVES TPMS ADAPTERS

The OEM TPMS is what it is, but sits perpendicular inside the rim, with this adapter sticking out with a shorter length.

Go figure. And... the more you know.

 

I'm getting a set of Vossens this winter and was trying to figure the TPMS, wether to go with the shortys like what you have or use OEM. Is there much of a difference in how the stems sit on the outside of the wheel or is it more about how they sit on the inside of the wheel?

 

Both.

In my case, the shorties are used solely because the stem section of the OEM sensors is too long, and interferes with the BBK on the front rims, but only with certain 19" diameter Vossens. So... OEM TPMS matched with these adapters so that the valve extension is shorter. This isn't a problem with 20" Vossens, only the 19's, and only on the front wheels when your car has the Akebono BBK.

I believe the intention of these "T-Valves" is primarily for aftermarket wheels where the orientation of the TPMS inside the wheel is compromised by the wheel design, although that's not why I need them. Do you follow? The previous two little pics become self-explanatory, once it clicks how the design works.

I just measured it, and the difference in size outside the wheel is exactly 1/2". Here's a pic of the standard valve stem that comes with the OEM TPMS:



And here's a pic of the T-Valve (shorty) stem adapter:

 

So with the shortys the TPMS isn't really affected it's just a shorter stem, but with the adapter the TPMS sits at a 90 degree angle, mainly for it to fit in a wheel that the design doesn't allow the OEM TPMS to sit vertically correct?

 

What I've been calling "shorties" are really just a T-Valve adapter, where the adapter stem is shorter than otherwise. Your OEM TPMS and Stem are still there, just at a 90 degree angle.



Alternatively, you could forgo the TPMS, and use shorty valve stems. Of course, then you'd have to live with the dash light warning.

 

Okay that makes sense now. Thanks for the clarification!

Nice addition.
