To make a long story short... I noticed that a buddy of mine has a set of scalloped tires on his Wing. He thought the $40 gauge that he had bought (gas station style chuck/gauge combo) would be accurate. It showed that he had 40lbs in the front. I checked it with my new Accutire digital gauge and it showed 32lbs. I understand Accutire brand are supposed to be accurate but I'm going to verify mine at work tomorrow since we have a calibrated gauge that is only used to verify other gauges.
