Thread: Lockable Valve Stem or Valve Stem Caps?

Here is the issue:

My left rear tire is deflated around 10 psi everytime I check, but it doesn't go flat. I let it go and I drive it around 23 psi for several week to verify that. The other tires stay constant at 33 psi.

So I when to Sears, and they told me that they checked my tire, valve stem, and wheel. They could not find anything wrong; there's no hole on the tire, the valve stem is not damaged and installed properly, the fitment of the tire is fine, and there are no cracks on the wheel. Apparently, somebody is deflatting my tire on purpose. This happened several other times on the same tire before and I notice it happens within one or two months when I check the tires; it is always down 10 psi but it doesn't go flat. I wonder who this chicken-shit is?

Does anyone know if there is such a thing as a lockable valve stem or valve stem caps? Your help will be greatly appreciated.

To those who maybe interested, I found this website that makes Billet Aluminum and Chrome Locking Valve Stem Caps:

From $29.95 to $35.95

Spin-Caps - Locking Valve Stem Caps

I had a similar problem. The tire store near me had to put a liquid sealer on the rim on both sides so the tire "sealed " to the rim when they mounted the tire. Bam , no more leak.

I'll have to ask the tire store about liquid sealer, thanks. But, just to be on the secure side, I'm going to buy locking valve stem caps because I never had this happen to a tire before. I'm confused why if there is leak; why doesn't it go flat?

Man sometimes the tire will have a nipple or a piece of dirt stuck in the bead between the wheel and tire, have a shop break the tire down and beadseal it and it should take care of the problem, alot of shops will just dunk the tire in a tank with like 40 psi instead of filling the tire up to a higher psi to find the leak

Thanks, next time I will talk to them about beadsealing.
