If you notice that your vehicle veers to one side when driving in a straight line, this may be due to the **tyres having different pressure on the same axle**.

- The vehicle's steering system is responsible for transmitting the movement of the steering wheel to the front wheels. If the vehicle veers to one side, a possible cause is that the tyres on the same axle do not have the same pressure. This affects the balance and steering of the vehicle, causing it to veer.

- Additionally, when the tyres are not properly inflated, it may be more difficult to move the steering wheel, and the tyres may wear out more quickly.

Therefore, it is important to ensure that the tyres are properly inflated and have the same pressure to avoid steering problems and uneven wear.
