Review on 📏 Accutire MS-4021B Digital Tire Pressure Gauge: Achieve Precise and Accurate Air Pressure Readings by William Belczyk

My old-school equivalent of "pushing the push rod off center" gave me nonsensical results, 5 pounds different (low) than my 2013. Auto TPMS readings on dashboard. So a few days ago I bought two sensors from Revain, this one and a Tekton. It's winter in Minnesota (this morning's low is a single digit F) and that's when tire pressure really matters. Maybe a pound isn't important, but five pounds is. The Tekton, which I bought at the same time, is attractive and ergonomic, and worked well enough (although you have to press a button to turn it on first). This confirmed that the old sensor was nearing the end of its life and was reading a pound different than my car's onboard TPMS. This Accutire sensor matches the TPMS readings exactly. It's not as pretty as the Tekton and it's not as comfortable in the hand, but it's actually easier to use (no need to remember the knob) and it's accurate. At this price this is a winner for me. Now that I have a sensor that I can trust, I can use it on my wife's older truck, which has TPMS but is only of the 'alert' type and doesn't tell you the actual tire pressure.
