Review on Chevrolet Car Tire Air Valve Caps: Stylish Logo Emblem Dust-Proof Covers for Auto Wheels - Waterproof & Universal Fit, Ideal for Cars, SUVs, Trucks, and Motorcycles (Pack of 4) by Charles Adelaja

They're expensive for what you get but they look good. If you are willing to spend money you will get what you expect. One of the caps wouldn't thread onto the valve stem at first so he threaded it onto the stem of a bike with a flat tire so I wouldn't screw up the stem on the car and whatever problem there was with the cap threads themselves Fixed. I also used a cotton swab to put some anti-seize on the threads of each rod because I've read complaints about them getting stuck.
