The Accutire MS-4800B is part of the Tire pressure gauge
test program at Consumer Reports. In our lab tests, Tire pressure gauge
models like the MS-4800B 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.
