Review on 🔍 GODESON Tire Tread Depth Gauge for Motorcycle, Car, Truck, and Bus - Professional Dial Type Gauge for Easy Reading in 32nds by Greg Bloom

I waited a bit longer to get this version as some other similar sensors weren't verified either but the one I got doesn't seem that good either to be. When placed on a flat surface with the stylus aligned with the ground, readings are taken for more than 32 seconds (see first photo). I checked this with my Starrett calipers and they confirmed that the tire scale is off by 1/32 when zeroed on level ground. If you zero the needle on the scale you can see the 1/32 indicator sticking out from the bottom (see second photo). I've been looking for a way to reset the calibration, but there doesn't seem to be a user-friendly way to zero it. Build quality was better than I expected, but it's disappointing that factory calibration is disabled. It will still work, but I need to add 1/32 to each dimension to get the right depth. If this were used by a tire dealer or service department, they would misrepresent true tread depth and tell customers their tires are more worn than they really are. Consider returning them and asking for a replacement.
