What do the numbers displayed on the tire pressure monitoring system represent?

In the tire pressure monitoring system, the upper number represents the corresponding tire pressure, while the lower number represents the corresponding tire temperature. The tire pressure monitoring system automatically monitors the tire pressure in real-time while the vehicle is in motion and alerts the driver to tire leaks or low pressure to ensure driving safety. The hazards of excessive tire pressure include: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear on the central tread pattern, shortening tire lifespan; Increases vehicle body vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts, leading to tire bursts.

I always pay attention to the numbers displayed by the tire pressure monitoring system, as they indicate the current pressure of my tires, usually measured in psi. For example, 30 psi is a common reading. If the number is too low, the tire can go flat, increasing friction and fuel consumption. If the number is too high, the tire becomes stiff, making the ride uncomfortably bumpy. The standard range for my car is 30 to 35 psi, as indicated on the small label by the door. Last month, the reading dropped to 26, so I immediately inflated the tires, avoiding a potential blowout. Now that winter temperatures have dropped, the numbers tend to decrease faster, so I make it a habit to check every two weeks. A bonus tip: Don’t wait for the warning light—developing a routine of checking can extend tire life by at least six months and save 5% on fuel. Safe driving is the top priority.

I think the numbers on the tire pressure monitoring system are absolutely crucial—they tell me the exact pressure in my tires. If the numbers are too low, the tire is like a deflated basketball, making the ride unstable and braking slippery; if the numbers are too high, the ride gets harsh with poor cushioning. The ideal range is between 30-35 psi. I once neglected it when the number dropped below 24, and it led to a terrifying blowout on the highway. Now, I check the numbers every time I refuel to avoid danger. The numbers can also be affected by temperature—in winter, they drop a few points, requiring a top-up. Maintaining the right numbers helps prevent accidents and keeps my family safe on the road. Remember, checking these numbers regularly is all about prevention.

I mistook the tire pressure number for the tire pressure reading, with the unit being psi, such as 32. If the number is too low, the tire deforms and consumes more fuel; if it's too high, the ride becomes bumpy. The standard range is 30-35 psi, check the door label. My habit is to check the number before driving, don't wait for the alarm. In winter, the number drops quickly, so air needs to be added. Extra: Occasionally use a pressure gauge to calibrate the TPMS reading for better accuracy.
