**Tires** are one of the main causes of traffic accidents due to mechanical failures. This is because tires can suffer from **punctures** or **blowouts**, which can lead to losing control of the vehicle. It is crucial that the tires are in good condition to avoid these problems.

- Tires must meet certain **quality characteristics**. They should not have **blisters, deformations, breaks**, or exposed cords. Additionally, the **tread** must have grooves at least 1.6 millimeters deep to ensure good grip and to remove water on wet roads.


- Checking the tires before a trip is an important preventive measure to avoid accidents. A tire in poor condition may be more prone to failure, especially in adverse conditions such as rain.

In comparison, the **brakes** and **steering** of the vehicle can also fail, but problems with tires are more common and therefore represent a more frequent cause of accidents related to mechanical failures.
