What is the equivalent of 300 tire pressure?

[OGabrielle]

Tire pressure of 300 kPa is equivalent to 3 atmospheres. The standard tire pressure for passenger cars is 2.4 atmospheres (commonly referred to as 2.4 kg). 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, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends and deforms 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. Methods for insufficient tire pressure: If no damage is visible, simply inflate to normal pressure and reset the tire pressure system; If a puncture is found during inspection, drive to a tire shop for repair and then reinflate; If the tire pressure warning reappears after inflation without any punctures, it may be due to air leakage caused by a deformed wheel rim. It is recommended to inspect and replace the wheel rim.
