Our tests look at digital, stick-type, and dial-type tire pressure gauges from four brands: Accutire, Intercomp, Gorilla, and Slime. We test for accuracy, ease of use, durability, and how the tire pressure gauges are are affected by ambient temperatures.
Keeping your car tires properly inflated is an easy maintenance chore that's vital to your safety. Underinflated tires build up excess heat as you drive, which can result in tire failure. With too little air pressure, tires can also wear faster and unevenly, waste fuel, and negatively affect the vehicle's braking and handling.
