Why You Should NEVER Use 32 PSI Tire Pressure

Is 32 PSI the wrong tire pressure? Not necessarily. The correct tire pressure depends on your vehicle, tire size, load, and manufacturer recommendation—not a universal internet rule. In this video, Carlos Herrera explains how to read the driver’s door-jamb sticker, what the maximum PSI on the tire sidewall means, and why you shouldn’t inflate to the sidewall maximum or change pressure based on the chalk test. Learn how to check tire pressure cold with a reliable gauge, how temperature affects PSI, what the TPMS light can and cannot tell you, and what to do about uneven tire wear or a pressure warning. We also cover heavy loads, EVs, replacement tires, nitrogen fills, and tire pressure’s role in handling and fuel economy.

Follow your owner’s manual and door-jamb sticker. If pressure keeps dropping or a tire wears unevenly, have the tire and alignment inspected. Check tire pressure monthly and before long trips—and don’t rely on guesses.
