https://www.cnet.com/roadshow/news/hacker-threat-hiding-in-car-tire-pressure-system/@eff @cooperq Wait, are the trackable tyre pressure readings coming from the tyres, or the car?
It seems like they'd need to be coming from the tyres, because the tyres know what pressure they're at.
But if the signals are coming from the tyres, why does it matter how old the car is? Surely you'd still be trackable in an old car, if it had new tyres on it?

They're mounted inside the tire.

@NocturnalNessa @eff @cooperq The sensors are installed inside the tires. I believe they are part of the valve stem assembly. They don't bother installing them in the tires of old cars that don't have tire pressure monitoring systems.

@NocturnalNessa @eff @cooperq Anything that would block the signal from being intercepted would probably also prevent communication with your car.
It might be easier to get the sensors removed from your tires. Doing so will make your car show the tire warning lamp but at least you'd know the cause!

@gneilyo i know. i was proposing this as an easier/reversible alternative to removing the sensor

@gneilyo i think if i wanted to go the route of hardware id see about making it not wireless. difficult, because youre wiring something that spins to something that (unless something is very wrong) does not spin. but i doubt its much throughput or along many channels or anything

@gneilyo you did just give me one other thought though: you could probably simply weaken the signal with covers without totally blocking it? so maybe your car could pick it up (though maybe less reliably) and an adversary 5m away could pick it up but an adversary 50m away could not?

@NocturnalNessa Do check back if you come up with something

@NocturnalNessa I actually need a new set because at least one of the ones in my car has a dead battery.
I wonder if any of them have the ability to trim the power output of their radios?
