Several years ago a co-worker of mine bought a new GM truck and offered me his tires and wheels for $400. Nice factory aluminum wheels & Firestone tires. Made my older Suburban look much newer, and cheaper than a set of tires from any shop. But his tire shop had to remove the factory sensors inside the tire/wheel before I got them and they put rubber stems in place of the metal ones, and sure enough, I lost two of them on the road and eventually has Les Schwab put steelies in and had no problems since.
On my older 96 pickup with aftermarket aluminum wheels I've had an ongoing corrosion problem with the steel valve stems. The local Les Schwab has been very patient since once or twice a year I bring it in with leaking valve stems, and they have to ream the hole and reinsert new stems. But they have never charged me since I'm using their Toyo brand tires.
