What does kPa mean on the dashboard?

[VanJake]

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.
