[QUOTE="Ridge Runner, post: 445105, member: 3775"] Here are the tolerances of gauges that use a fully geared, solid brass precision movement with bronze bourdon tube, I get all my Gauges and measuring gizmo's Calibrated by someone I know at British Aero Space, he even gives my Straight Edge's the once over. The mechanical accuracy rating is 2% from 25% to 75% of scale and 3% below 25% and above 75%. A 15 psi tire gauge is accurate to 0.5 psi from 4 psi to 11 psi and is calibrated to 0.25 psi at 7.5 psi. A 30 psi tire gauge is accurate to 0.6 psi from 8 psi to 22 psi and is calibrated to 0.5 psi at 15 psi. A 60 psi tire gauge is accurate to +/- 1.2 psi from 15 to 45 psi and is calibrated to 1 psi at 30 psi. A 100 psi tire gauge is accurate to 2 psi from 25 to 75 psi and is calibrated to 1.5 psi at 50 psi. A 160 psi tire gauge is accurate to 3.2 psi from 40 - 120 and is calibrated to 2 psi at 80 psi.
