maybe a dumb ? but...

yep

 

Yeah, you'll be able to see a little module on the inside of the rim when you take the tires off.

 

they are actually a part of your valve stem....you will need to take it apart and reinstall it in your new rims...make sure you which ones are which...if you get them mixed up it will play havoc on your computer..meaning the light will tell you its one tire thats low while its actually another...

 

They're not on the valve stem on the new F-series. I should've taken a pic when I put my new tires on.

 

they mustve changed them since i was in the tire shop....but its basically the same principal....dont get them mixed up though....

 

ya... i got one in my truck.. ill go get it after the belts shut down here at work

 

its blue... and held around the wheel with a bigass band

 

oh...ok...i know what your tALKING ABOUT....still the same principals apply there too....just be very gental with them while mounting or dismounting tires...and dont get them mixed up for the 3rd time,,,lol

 

you can mix them up

 

really...are you sure...the last ones i messed with were very persistant that they had to be on the same place...
