I have studied several different tire valve caps and am very satisfied with these SAMIKIVA brass tire valve caps. My goal was to make sure I found the ones that screwed in all the way and didn't stick out. In the end I was very pleased when I put them on our 2014 MB C250 and saw that they were completely screwed up. I'm sure there are other brands that fit perfectly, but there are some that don't. So you should be happy with that if you're looking for the same thing as me when it comes to installation. Although fit was the most important factor for us, the color and style of these caps proved great for the bikes we have. Let's see how they will behave over time driving the car in different conditions but judging by the material and their feel I'm confident.
