I finally got a chance to try Tire Caliber. 75psi As you know, many of these sensors are in terrible condition and of questionable accuracy. My new sensor has met all my expectations. It is easy to use and reaches the inside of the double valve stem very well. The sensor function allows easy and quick reading of the tire pressure, no matter where the valve stem is located. A knob on the stem makes it easy to depressurize each tire, ensuring all tires take their share of the load. Overall, this is the best tire gauge I've ever used. I would recommend this to everyone.
