17" wheels to 21" wheels with TPMS

[houston]

I have an 08 V6 with 17" rims and tires. I am going to oem 21" rims and tires. Can you tell me how to change the tire pressure sensors? any other mods needed?

Just unbolt the sensors from the old wheels and install them on the new wheels.

Where are they located? I did not remove the wheels yet. Are they on the wheel stems inside or outside?

[Loren]

They are mounted to the inside of the valve stems (items 1 to 4).

If you plan to keep the 16" wheels, then you can purchase just the wheel sensors and have both sets of wheels/tires able to be monitored by the TPMS system. The Tire Rack sells compatible sensors, I don't know what the dealer cost would be but that is another option.

In your post you said "OEM wheels and tires", if you are ordering them you would be able to specify the TPMS option as well.
