Same Gauge, two different readings!
Bruce,
I like you made an early owner purchase of a Milton tire gauge. I did it while at Holiday Tours shop in Randleman, NC - home of the Petty Clan. I immediately began reading tire pressures, as the sales truck drove out the gate. I found that the readings were either on the money or 10 lbs. off. I checked the gauge and found that the two psi scales were marked off by 10 lbs one from the other. I compared Holiday's "master gauge" against mine and crossed out the off side using permenant black marker. No problems since then.
Go figure where "Quality Control" has gone today.
