What does kPa mean on the dashboard?

kPa on the car refers to air pressure. kPa stands for kilopascal, abbreviated as kPa, which is the unit of air pressure. In vehicles, kPa generally indicates the tire pressure. The standard tire pressure varies depending on the tire type and vehicle model, as different models have different weights, heights, and tire sizes, thus requiring different tire pressures. The standard tire pressure for standard tires is 240kPa-250kPa, while reinforced tires have a standard pressure of 280kPa-290kPa. Below is some relevant information about air pressure: 1. Air pressure is crucial for tires; both too high and too low pressure can shorten the tire's lifespan. Low pressure increases tire deformation, easily causing cracks on the tire side, along with flexing movements that lead to excessive heat, accelerating rubber aging, fatigue of the cord layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulder. 2. Excessive pressure causes the tire cords to overstretch and deform, reducing the tire's elasticity and increasing the load on the car while driving. In case of impact, it may lead to internal cracks and blowouts. Additionally, excessive pressure accelerates tread wear and reduces resistance to punctures.
Last time I was driving, I noticed the abbreviation 'kpa' on the dashboard, which actually stands for kilopascal, a unit of tire pressure. Having driven for so many years, I know that each tire has a recommended pressure value, usually found on a label attached to the door frame, with the unit mostly in kpa. Tire pressure that's too low or too high can affect handling. I once forgot to check, and as a result, my fuel consumption increased and the tires wore out quickly. Since then, I always keep a tire pressure gauge handy to measure it myself. The ideal value is generally around 200 to 250 kpa—too low and it's prone to blowouts, too high and the ride becomes bumpy. Regularly inflating to the manual's recommended value saves fuel and ensures safety; don't overlook this small detail. If the dashboard warning light comes on, stop and check immediately or go to a repair shop—new cars nowadays come with this monitoring feature.
