We like the old fashioned method of a tire gauge once in a blue moon. Unless you develop and obvious leak, this system is pretty fail safe and the tire monitors we looked at added cost, which is fine if you prefer that, and they presented moisture issues from the dunking. There are some air caps that are color coded to show your pressures and we have thought about those. Though we have not tried them yet. Those would show a quick look and tell tale, if they would hold up under the changing pressure and water absorption.
