To ensure **safety** while driving, it is important that a vehicle's **tires** meet certain characteristics. Although different tires can be used on each wheel, it is essential that the **two front tires** are identical to each other and the **two rear tires** are also identical. This is because:

- The tires must have an appropriate **tread** to ensure good grip on the road, especially in rainy conditions.
- The **compatibility** between the front and rear tires helps maintain the vehicle's **balance**, preventing vibrations and irregular wear that can cause accidents.
- A good condition of the tires, without deformations or cracks, is crucial for the vehicle's active safety.


Therefore, although some variability is allowed, maintaining **uniformity** between the front and rear tires is fundamental for safe driving.
