The TireTek Truck-Pro Tire Pressure Gauge is built to last with a tough steel shaft & casing, solid brass movement & fittings, with a reinforced acrylic display window and rugged ‘gear-style’ surround to protect your gauge from day-to-day drops and knocks. No plastic used!
Yes, the TireTek Truck-Pro Tire Pressure Gauge will retain the pressure reading when removed from the tire valve until the pressure release / bleed button is pressed on the side of the gauge stem. You can also take an accurate pressure reading while still on the tire valve, like a standard gauge, however this is a very useful feature to have when trying to read the dial in bad light conditions for example.
Yes! While the TireTek Truck-Pro Tire Pressure Gauge is pressed on your vehicle’s tire valve and showing a reading, press the button on the side of the gauge. This will allow you to release air to deflate or ‘bleed down’ your tire pressure. You can keep an eye on the pressure reading by periodically releasing the bleed button to check pressure, easily reducing tire pressure to the exact level desired.
Our Truck-Pro Tire Gauge is a highly accurate mechanical pressure reading instrument, designed with a fully geared, solid brass precision movement and bronze bourdon tube movement mechanism. Unlike traditional plunger-type gauges or modern Digital tire pressure gauges, the bourdon tube movement is not affected by changes in temperature, humidity, altitude or air stream contaminants. Our certified mechanical tire pressure gauges will perform reliably at low temperatures and do not rely on batteries to work!
ANSI is the acronym for the American National Standards Institute, a non-profit organization that oversees the development of voluntary consensus standards for products in the United States.
B40.1 is the specific standard that has been issued by ANSI for pressure gauges, with dial-type pressure gauges having four grades of accuracy: A, B, C, and D.
All of our TireTek tire pressure gauges meet ANSI B40.1 Grade B specifications, which is the highest accuracy standard typically used for tire pressure measurement (with ‘A’ being the most accurate and used mainly for industrial applications).
In practice the ANSI B40.1 Grade B certification means that the mechanical accuracy rating of our tire pressure gauges will be ± 2% from 25% to 75% of scale and ± 3% below 25% and above 75%. So a 60 psi range tire gauge is accurate to ± 1.2 psi from 15 to 45 psi and is calibrated to ± 1 psi at 30 psi.
Modern calibration is performed by computers using electronically controlled mechanical adjusters to fine-tune the components. The TireTek range of modern Bourdon tube movement mechanical tire pressure gauges are precisely rolled and calibrated in this way to specific dimensions that should not require any further calibration over their lifespan.
