Proper tire pressure, often overlooked, is crucial for safety and efficiency. Under-inflated tires increase rolling resistance, wasting fuel and causing them to overheat and wear unevenly. Over-inflation reduces your tires' footprint, compromising grip and making for a jarring ride. Checking your pressure when tires are cold, using a reliable gauge, is a simple weekly habit that also improves handling and extends tire life.
