My Truck read outs always show the front right about 3 psi above the gauge. The others are within 1 psi of the gauge.
I inflated the Mountaineer with a new charger/compressor thing a few weeks ago. I set it at 80 psi. When done, I check with a digital gauge. Read out was 2 psi less. So I bumped things up and got 80 on the gauge. Then I put the TST on it. It read another 2 psi down. So compressor was 82, gauge was 80, and TST was 78!!!!
