Is the tire pressure the same for front and rear tires of a car?

Is the tire pressure the same for front and rear tires of a car? The normal tire pressure is usually between 2.2 and 2.5 bar. Tires are circular elastic rubber products assembled on various vehicles or machinery to roll on the ground. The functions of tires are: 1. To prevent severe vibration and early damage to automobile parts, adapt to the high-speed performance of the vehicle and reduce noise during driving; 2. To support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions; 3. To transmit traction and braking torque, ensuring good adhesion between the wheel and the road surface, thereby improving the car's power, braking, and passability.
When it comes to whether front and rear tire pressures should be the same, after driving a car for ten years, I've found this isn't a fixed rule. My Volkswagen manual clearly states the recommended pressure is 32 psi for the front tires and 30 psi for the rear tires, because the engine's weight up front puts more load on the front tires. Ignoring this can make steering feel floaty and increase braking distance—I once nearly slid off the road because of it. Now, I check with a tire gauge every time I refuel. In summer heat, tire pressure rises, while in winter it drops, requiring constant adjustment. Load is another factor—when the trunk is fully loaded, I increase rear tire pressure to around 34 psi for stability. Bottom line: don’t cut corners. Always refer to the sticker on the door frame or the manual—safety first.
