To register pressure they must come through a slip ring on each hub, so its
how good are the seals and how long will they last. This technology is a by
product of motor racing, where the cars are stripped down and rebuilt after

Why not let one tyre down and compare the electronic reading to your manual
Which manufacturers use "slip rings" to convey TPM data? That's the first I've
