Slime 20048 tire pressure gauge

About

The Slime 20048 is part of the Tire pressure gauge test program at Consumer Reports. In our lab tests, Tire pressure gauge models like the 20048 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.
