To ensure the **safety and proper functioning** of the vehicle, it is essential that the tires always have the **pressure recommended by the manufacturer**. This pressure is specifically determined for each type of tire and vehicle, ensuring that the tires adequately support the load and weight of the vehicle.

- **Pressure lower than recommended**: If the tires have less pressure than necessary, they heat up and deform, leading to premature wear. Additionally, the vehicle consumes more fuel, is less stable, and has a higher risk of skidding on wet surfaces. There is also an increased possibility of the tire bursting.

- **Pressure higher than recommended**: Excess pressure reduces the tire's contact with the ground, decreasing its grip. This causes uneven wear, mainly in the center of the tire, and makes the vehicle vibrate more, as the tires do not absorb road irregularities well. Additionally, the shock absorbers may be damaged more quickly.

For these reasons, it is crucial to **check the tire pressure at least once a month** and before making long trips or heavily loading the vehicle. Maintaining the correct pressure not only extends the life of the tires but also improves the safety and efficiency of the vehicle.
