Why should the tyre pressure in the front of cars be usually lower than in the rear? In the user manual it is usually recommended to increase the tyre pressure when travelling or full load. Normally a car is heavier in the front than in the rear when it has engine and gearbox in the front. In addition, the tyre pressure is flatter when the tyre pressure is too low or higher, is less stable and is also more deformed, which should be avoided. In other words, the tyre pressure of a car, in the front, would have to be higher than in the rear!
