Review on AIEX 8 Packs Aluminum Tire Valve Stem Caps With Gasket Universal Hexagon Valve Covers Replacement For Cars Tires & Wheels via Accessories & Parts by Braxton Jackson

Good thing they give you 8, you'll need them so don't share another set with a mate! You can see in my photo that the tire on my tire was changed about 6 months ago. The copper on the right I just took off after running a little over a year (bought April 21st) to replace it with the 'new' one on the left which I found on 4 additional items kept and changed them a little bit. everything off. If I had to guess, their color lasts 5 to 6 months. It's actually kind of weird how they disappear too, not like peeling paint or anything, just disappearing.
