What can cause a vehicle to pull to one side during driving?

A vehicle pulling to one side while driving is commonly a result of misalignment or uneven tire pressure. When the front end of a vehicle is misaligned, the wheels do not point in the same direction, which can cause the vehicle to veer to one side. This misalignment can occur due to hitting potholes, accidents, or general wear and tear over time.

Similarly, uneven tire pressure can also lead to pulling. If one tire is significantly under-inflated compared to the others, it can create a drag that affects steering and causes the vehicle to pull towards the affected side. Maintaining even tire pressure is crucial for optimal handling and stability.

Other factors such as brake issues or worn suspension components can also contribute to pulling, but in the context of the choices provided, misalignment or uneven tire pressure is the key reason a vehicle might pull to one side while driving.
