Chances are your tires actually DO have radio emitters in them - tire pressure sensors are wireless and send their measurements out on the 433 MHz band.
Wow, didn't know they were UHF, figured it would be some GHz nonsense... Now I kinda want to build a tyre pressure sensor receiver.
A cool use for that would be a warning screen in your garage if you pull in with low tire pressure.
I use 433 MHz buttons, switches and sensors for my smart home stuff, so I have a receiver (generic DVB-T SDR dongle) listening, and I can see all the tire pressure signals that passing cars send out.
