What types of tyre pressure gauges are there?
There are three types of pressure gauges: stick, dial, and digital gauges. Stick gauges are long metal sticks with rods that slide out of the valve end. To use it, first remove the cap off your tire valve. Insert the rod into the valve, then take the open end of the stick gauge and press firmly. The air will then rush out of the tire into the stick. The white stem will push out of the other end and indicate the tyre’s PSI. Dial gauges have small clock-like faces on them that resemble a speedometer. After taking the valve cap off the car, apply the valve end of the gauge into the car’s valve. Air will rush in and move the needle which will stop on the number that indicates your tyre’s PSI. Digital gauges work similarly to dial gauges; simply take the valve cap off the car, apply the valve end, and the gauge will display the PSI.
