I get so tired of messing with the cheap tire pressure gauges. They are really inaccurate, and are a pain to keep with you. What if there was a way to always be able to check your tire pressure and not have to keep a gauge on your person? Yanko Designs has developed a digital tire gauge that replaces your tire cap. This gauge has a digital display and you can see the current tire pressure with the push of a button. This battery operated device is perfect for making sure your tire pressure is even, and makes it a lot easier than having to take the cap off every time.
