Review on 🔧 Hromee Automatic Tire Deflators Kit: Offroad Vehicles, Cars, Trucks - Adjustable Air Deflating Set with 80 PSI Pressure Gauge & Valve Core Repair Tool by John Murphy

My first wish for them is that they have some kind of pre-installed PSI markers or some notches. when turning, so that you get the right psi value quickly and consistently. It takes trial and error, but I've found that if you set the tire to the desired PSI, for example, and then connect each of the deflators, they can give you different PSI ratings for the same tire. and make sure they are set to that psi. You can see that on some deflators the nut is not in the same position and if you use it on other tires they will output different psi. In one example, one of the deflators is somehow off by about 5 psi. More tests need to be done, maybe I can perfect it in a day.
