TERRIBLE! NOT ORDER! My wife had a constant problem with losing her plastic tire valve caps so I decided to give her Jeep some flare and ordered them as they looked great and had a set screw to keep them from falling off. Terrible decision. The set screws loosen so easily that it is almost impossible to remove them from the valve stem. They eat the hell out of the valve stem and are a terrible product. I hate to say this, but I want others to know about our experiences with them. We ended up buying more plastic valve caps and I will continue to do so before I break the valve stems.
