Multiple Choice

Which instrument is used to verify tire pressure?

Measuring tire pressure requires a device that reads pneumatic pressure accurately and specifically for tires. The calibrated tire pressure gauge is designed for that purpose, with a scale in psi and a valve stem connection that provides an accurate reading of the tire's actual pressure. This ensures you inflate to the correct level and maintain proper tire performance and safety. A tape measure only measures length, and a stopwatch measures time, so they cannot determine pressure. A general calibrated gauge might not have the correct range or the appropriate connection for tire valves, risking inaccurate readings. Using a tire pressure gauge that is calibrated for tires gives you reliable, repeatable results every time.
