How to Check Tire Pressure?
2 Answers
Methods to check tire pressure: You can view the feedback information from the car's dashboard or the central control display's onboard computer, use a tire pressure gauge to measure, or observe the number of tire treads in contact with the ground. The normal tire pressure for a car is between 2.3 and 2.5 bar. Due to environmental factors, tire pressure can be slightly higher in winter and lower in summer. Symptoms of overinflated tires: 1. The vehicle reacts noticeably to road conditions while driving, with larger tire bounce over bumpy sections; 2. The steering wheel feels lighter at high speeds, making turns more agile; 3. Reduced friction between the tires and the ground lowers fuel consumption to some extent, but the vehicle is more prone to skidding during high-speed turns. Symptoms of underinflated tires: 1. The vehicle reacts sluggishly to road conditions while driving, with reduced bumpiness; 2. The steering wheel feels heavier, increasing steering resistance; 3. Increased friction between the tires and the ground leads to higher fuel consumption.
As a car enthusiast, I often check tire pressure myself—it's a fundamental skill for ensuring driving safety. First, you'll need a tire pressure gauge—there are digital and manual needle types available on the market, and I prefer digital ones for better accuracy. Make sure the car has been parked for at least three hours with cold tires before checking to get accurate readings. Then, press the gauge firmly onto the tire’s valve stem and read the stabilized measurement, comparing it against the recommended values (usually 30-35 PSI) listed in your vehicle manual or on the label inside the driver’s door. If the pressure is low, inflate the tires using a home pump or a gas station air compressor. Remember to check every four weeks, especially during seasonal changes, as temperature fluctuations affect tire pressure. I find this method simple yet effective—it prevents uneven wear and blowouts while saving fuel costs. After adjusting my tire pressure before a recent road trip, I saved 5% on fuel consumption.
