Which Gauge is Right for Me?

Bourdon Tube style pressure gauges reach their peak accuracy in the middle 1/3 of the scale. Given this, Milton recommends purchasing a tire gauge in which your most common readings fall within the peak accuracy sector of the gauge. If you commonly test your car tires at 30 PSI, a 60 PSI gauge is ideal. This pressure range would offer you peak accuracy at your desired pressure, as well as cover a large enough range in the case of overinflated tires.

Tire Gauge Accuracy:

All of our dial tire gauges are ANSI Commercial Grade B gauges (meets ANSI B40.1 Grade B specifications). Unlike piston-plunger-type gauges, the bourdon tube movement is not affected by changes in temperature, humidity, altitude or air stream contaminants.

The mechanical accuracy rating is ± 2% from 30% to 60% of scale and ± 3% below 30% and above 60%.
