To ensure **good performance and safety** in the vehicle, it is crucial that the tires are inflated to the **manufacturer's recommended pressure**. This recommendation is based on specific tests for each vehicle model, ensuring that the tires adequately support the car's load and weight.

- **Pressure lower than recommended**: It can cause the tire to heat up, deform, and wear out faster. Additionally, it increases fuel consumption and reduces vehicle stability, increasing the risk of skidding on wet surfaces and the possibility of blowouts.

- **Pressure higher than recommended**: It reduces the tire's contact with the ground, which decreases grip and causes uneven wear, mainly in the center of the tire. It can also cause vibrations in the vehicle and damage the shock absorbers.

For these reasons, it is essential to **check tire pressure at least once a month** and before long trips. This ensures that the tires operate optimally and prolongs their lifespan.
