I have 2 digital tire%gauge s and 2 analog. All 4 agree with each other within about 2 psi. However, the on vehicle screen tire pressure monitor reads low. In order to achieve the specified 33psi for fronts and 41 psi for rears I need to go 4-5 psi above that number on my other gauges. Now since they all agree with each other, it should seem the car is somehow reading low. I have performed 3 system resets and now have the exact specified numbed on my screen, but the rears for example check at 46psi with all my other gauge s. This is too high and the car seems to ride hard of course. I know such exact precision is not required for simple daily driving, but the stupid short life and high price/ poor selection of the 20 inch ecopia makes me want to treat them as well as possible.
