The value of having your tires etched is minimal if it is not widely know that tires are marked with identifying numbers or marks. Marking a tire is only a deterent when it is widely used, and know to the public, theives and the buyers of stolen goods. The value of stolen goods are reduced when there is a danger that the theives or buyers of the stolen goods will be caught.
On the matter of wheel locks, I was told that they are not as effective on steel wheels and can easily be removed becuase they are not recessed into the wheel like they are in alloy rims. I am installing 2 sets of wheel locks ( one set retained from my last car before the trade ) on my steel wheels, as this will slow them down or may deter the theives from stealing the winter tires. I have also installed an alarm system in the car and flashing LEDs to warn off car and tire theives.
