How to Read a Tire Pressure Gauge?
2 Answers
The method to read a tire pressure gauge is as follows: 1. The tire pressure gauge has two scales, one is in imperial units (pounds per square inch), and the other is in metric units (kilograms per square centimeter); 2. Observe where the pointer points to determine the pressure. The hazards of overinflated tires include: 1. Reduced friction and adhesion of the tire, affecting braking performance and tire lifespan; 2. Decreased resistance to punctures, increasing the risk of a blowout; 3. Accelerated wear on the central tread pattern, reducing tire lifespan, increasing vehicle vibration, and affecting the lifespan of other components; 4. Excessive stretching and deformation of the tire cords, reducing elasticity and increasing the load on the tire while driving, thereby decreasing puncture resistance; 5. Increased susceptibility to punctures from sharp objects like nails or glass, leading to internal cracks or blowouts upon impact.
I always make it a habit to check tire pressure when the car is cold, as readings are most accurate when tires are cooled down. Grab a tire pressure gauge—I usually find digital ones simpler to use: remove the valve stem cap, press the gauge firmly onto the valve to ensure a tight seal, and within seconds the screen displays the reading. The units are typically PSI or kPa; after noting the value, I compare it with my owner’s manual—recommended pressures vary by vehicle model, with SUVs often around 32 PSI. Remember to check every tire—don’t skip one out of laziness! I do this monthly to save money and stay safe; underinflated tires wear out faster and may even blow out, risking safety. Since adopting this routine, highway driving feels much more reassuring.
