What is the appropriate difference between front and rear tire pressure?

[StAndrew]

Tire pressure difference within 0.1 bar is normal. The standard tire pressure is 2.4-2.5 bar, while reinforced tires have a pressure of 2.8-2.9 bar. The maximum pressure should not exceed 3.5 bar. Tire pressure refers to the air pressure inside the tire. In automotive maintenance, the engine is the heart of the car - engine failure will lead to the end of the vehicle's life. Tire pressure is like the blood pressure of a car, as it plays a crucial role in the vehicle's performance and power. Reasons for different front and rear tire pressures: The car's center of gravity position and drive form vary; The number of passengers in front and rear may differ; Front-wheel-drive cars have higher front tire pressure, while rear-wheel-drive cars have higher rear tire pressure. Effects of low tire pressure: Increases friction coefficient with the road surface, leading to higher fuel consumption; Causes heavier steering and tendency to drift, compromising driving safety; Increased movement of tire components leads to excessive rolling and abnormal heat generation; Reduces the functionality of cord fabric and rubber.
