How to Check Car Tire Pressure?
2 Answers
Methods for checking car tire pressure: First, prepare a tire pressure gauge, locate the position of the original tire pressure label, press the tire pressure gauge against the tire valve to measure and read the value. Remember to replace the valve cap after checking the tire pressure. You can also check the tire pressure through the display on the dashboard. If the tire pressure is abnormal, the tire pressure warning light will illuminate on the display. The normal range of tire pressure is between 2.2 and 2.5 bar. Excessive tire pressure will concentrate the vehicle's weight on the center of the tread, leading to rapid wear of the tread center. Insufficient tire pressure can cause uneven tire contact area, increased wear, higher rolling resistance, and increased fuel consumption. Tire pressure has a significant impact on driving safety and the lifespan of the tires.
As a seasoned driver with over a decade of experience, I consider checking tire pressure one of the most fundamental maintenance tasks. Just buy a tire pressure gauge—either the stick-type or digital one will do—they're affordable and durable. The process is simple: in the morning before driving when the tires are cool, remove the valve cap, firmly press the tire pressure gauge onto the valve stem, and wait a few seconds for the reading to appear. Then, refer to the recommended value in the owner's manual or on the sticker on the door frame, such as 30 PSI or 2.1 BAR. If the pressure is too high, gently press the valve to release some air; if it's too low, use an air pump to add more. Checking monthly can significantly save fuel—I've personally tested that proper tire pressure reduces fuel consumption by 5%-10%, while also preventing excessive tire wear and extending their lifespan. Additionally, don’t overlook the spare tire—check it regularly to ensure safe driving. Developing this habit is easy, and starting with driving habits can help prevent problems before they arise.
