WTB tires pressure sensors, Broken or dead.
 

I am looking for mainly BAD tires pressure sensors. Not looking to spend anything for them since its for research.

if you have good ones, maybe ill consider.

Preferably GM ones but ill take any type for free.

Let me see what I can do for you... Snap in type like Fords or bolt in like type like Asian cars?

as long as its the valve stem direct type, it doesnt really matter. i need to inspect the type of electronic circuits they commonly use.

My friend owns a Cooper tire place, his employees brake them every once in awhile, I'll let him know to keep them for you if they happen to break some.
