Introducing the Accu-Pressure Safety Caps. Just replace your standard tire caps with these visual indicators and you’ll never have to guess whether it’s safe to drive or not.

So keep yourself and family safe, keep a little more of that hard-earned cash in your pocket, and save the environment by getting better mileage.
