March 17, 2022 – Tires are precisely engineered to perform multiple, often conflicting, functions: They must grip the road securely, cut a safe path through puddles and snow, turn with precision, contribute to good fuel economy, help smooth the ride, and be strong enough to resist damage from potholes and road debris.
In order to function properly, tires must be filled with a specific amount of pressurized air. Too much pressure can be problematic, but far more problematic and, unfortunately, more common is having too little tire pressure.
Having a good tire-pressure gauge in one hand and the air hose in the other means you can set the pressures precisely. Check your owner’s manual or the driver’s-side door jamb for the proper pressures at which your tires should be set in the cold.
