I have powder coated aluminum rims that come with valve caps. Good at it. However, I took it to get new tires. When I got home, I realized something was wrong. Upon closer inspection, I noticed that one of my valve stem caps was missing. I looked everywhere and even called the tire shop and of course they didn't know anything. So my next best thing was to look to Amazon for a replacement. That's when I found these awesome valve covers. They fit perfectly and the fact that they are 2 pieces. Nobody wants that, so leave them alone. Nonetheless, they fit and look great. I love these cases so much I have replaced all 4 and look forward to purchasing a second set just in case.TH%%
