How to Check if Car Tires Have Air?

Methods to check if car tires have air: Radial tires, commonly known as low-pressure tires, are normal as long as the flatness is not too low. If you press down with your foot and feel significant elasticity rather than softness, it's normal. High-pressure tires, which are bias-ply tires with inner tubes, are normal if the shoulder area does not protrude when viewed from the front and the contact area with the ground appears similar to usual when viewed from the side. Tires are circular elastic rubber products mounted on various vehicles or machinery for rolling on the ground. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high or low temperatures during operation. Therefore, they must have high load-bearing capacity, traction performance, and cushioning performance, while also requiring high wear resistance, flex resistance, and low rolling resistance and heat generation.
I've been driving for over a decade, and checking tire pressure is a weekly habit for me. It's quite simple: first, park the car on level ground, crouch down, and look at the tires from the side. A deflated tire will appear flatter on the outer side, not as round as when it's fully inflated. Gently press the tire with your hand—if it feels soft and lacks elasticity, the pressure is likely low. Of course, the most accurate method is using a tire pressure gauge. You can buy a portable one for just a few dozen bucks, screw it onto the valve stem, and read the measurement—typically around 230 kPa for the front tires and 240 kPa for the rear, but always check your vehicle's manual for specifics. Never ignore low tire pressure—it increases fuel consumption, accelerates tire wear, and raises the risk of a blowout, especially before long trips or highway driving, which is why I always double-check. Remember to measure at least once a month, and more frequently during seasonal temperature fluctuations—safety first!
