How does the TPMS work, and where in the wheel is it hiding? I looked at the valve stems and they look just like normal valve stems to me...? Sorry for the stupid questions, but the search has yielded no useful info on it...

 

it is inside the rim. about 1 x 2 " activated by motion...

i think low is 24 lbs and high is 44.
