Review on Corrosion Resistant Leak Proof Universal Motorcycle by Shawn Torres

A great way to add some style to your tires. The blue ones were added to a 2007 Subaru Outback and they matched the valve stems perfectly. Even better than the cheap ones that come with tires. I thought there was a rubber ring in the lid, but the "O-ring" mentioned in the ad is just part of a hard plastic insert.
