Low tire warning info????

[Orland Dewey]

Hello,
I need to find new "decals" for my "Tire-Tele" low tire pressure
warming system. I called Airstream and they had no Idea as
to what I was talking about as they never installed anything
like that (my manual says they did). I tried looking up info on
computer but nothing works. These new decals go on the rims so
the tire repair shop doesn't damage the sending unit inside of the
tire. 1985 325 454 MH
