First things first. This fits onto the TPMS valve stem. I work for Good Years (15+ years ago). If like me you hate the lack of a valve stem cap, get this product. This cap is for the valve stem of your car tire that is equipped with an air sensor. Will it fit in a car without TPMS: All caps are probably of good quality. They all have a black inner seal to keep debris out of your valve. The 2012 Honda Civic EX1 sucks, but the 10 is excellent.
