Is a tire pressure of 280 too high?

[McCharlotte]

A tire pressure of 280 kPa is slightly high, which can increase the load on the car during driving and make it more prone to tire blowouts. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening its lifespan; Increases body vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of the tire cords, reducing tire elasticity and increasing the load on the car during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more likely to be punctured, leading to internal cracks, blowouts, and tire bursts. Methods for addressing insufficient tire pressure: If no damage is visible, simply inflate the tire to the normal pressure and reset the tire pressure system; If the tire is found to be punctured during inspection, drive to a tire shop promptly for repair and reinflation; If the tire pressure warning appears again after inflation but there is no puncture, it may be due to air leakage caused by a deformed wheel rim. It is recommended to inspect and replace the wheel rim.
