Gorilla Automotive TG1 tire pressure gauge

A stick gauge that performed well in our tests, but it can be hard to get a good seal on some valve stems.  Accuracy is just fair in our cold temperature test. Limited range makes it suitable for many passenger car tires.

About

The Gorilla Automotive TG1 is part of the Tire pressure gauge test program at Consumer Reports. In our lab tests, Tire pressure gauge models like the TG1 are rated on multiple criteria, such as those listed below.

Accuracy: Accuracy is based on a comparison of each model against a known calibrated master gauge at various pressures, and at cold, room, and hot temperatures. Cold and hot temperatures simulated storing the gauge in a car in winter and summer temperatures.

Ease of use: Ease of use is primarily an assessment of pressure readability and how easy is it to take a pressure reading on an inflated tire.

Durability: Each model was checked for accuracy after a drop test of approximately 30-inches from a table to judge durability.
