I am waiting my new wheels and was wondering if I can remove the tpms from my oem 19 wheels to the new aftermarket wheels?

 

Absolutely, though you probably want new valve stems if you do that.

A TPMS sensor consists of a couple of parts: the winged sensor contains the electronics, and the valve stem which screws into it (parts C-F in this diagram).

The issue is that removing the stems damages them, so you want new ones when changing wheels.

 

Where can I buy them ?

 

They're a common, universal part. Any tire store should sell them.

If you want to buy them yourself, places like J.C. Whitney carry them.

 

Thanks

 

Its better for me to contact the agency where I am buying the wheels and the tires and ask them to put new tps

 

Are you sure TPMS sensors are universal? Factory wheel packages from Porsche have 2 versions for the same wheel/tire depending for pre or post face lifted Panamera. The version for the current Panamera has TPMS II which I assume is different from TPMS I for the previous Panamera.

 

The sensors are highly specific. The valve stems are a universal part. Look at the diagram I posted - part B is the section that must match the car.
