Usually, the recommended psi for passenger cars ranges between 30 to 35 psi, while light trucks and SUVs may require higher pressures, typically between 35 to 45 psi. Heavy-duty vehicles, like commercial trucks and buses, often have tire pressures exceeding 80 psi.
It's important to maintain the recommended tire pressure to ensure optimal vehicle performance, fuel efficiency, handling, and safety. Under-inflated tires can lead to increased fuel consumption, reduced traction, and uneven wear, while over-inflated tires can result in a rough ride, reduced shock absorption, and increased risk of tire failure.
To accurately measure tire pressure, use a reliable tire pressure gauge. Check the pressure when the tires are cold, before driving, to get the most accurate reading. Adjust the pressure as necessary to match the recommended psi, and consider checking tire pressure regularly (e.g., once a month) to maintain proper inflation levels.
