What is 2.5 tire pressure in kPa?
1 Answers
2.5 tire pressure equals 250 kPa. The unit of car tire pressure 2.5 is bar, which is a commonly used unit of pressure. As shown in the figure below, the black inner circle unit is bar, and the red outer circle unit is psi. Tire pressure value refers to the cold tire pressure. If the vehicle has been parked for more than 3 hours or has not traveled more than 1.5 kilometers, checking the tire pressure at this time is the most accurate. After driving, heat is generated inside the tires, so an increase in tire pressure is normal, usually about 0.3 bar higher than the cold tire pressure. Do not reduce the tire pressure because of this. Hazards of low tire pressure: The increased contact area with the ground will affect the car's fuel consumption performance. Severe deformation of the tire sidewall accelerates the aging of internal steel wires and fabric layers, reducing tire lifespan. It cannot ensure normal contact between the tread and the road surface. In the case of emergency braking, due to the tire shoulder, the reduced contact area may decrease braking performance. Hazards of high tire pressure: When driving on bumpy roads, the car body will experience noticeable vibrations. The vehicle's weight will concentrate on the center of the tread, causing rapid wear in the central part of the tire and also affecting tire lifespan. With a reduced tire contact area, emergency braking on low-adhesion roads will result in longer braking distances, increasing the risk of rear-end collisions.
