What does a driver need to maintain to ensure good traction?

To ensure good traction, a driver needs to focus on proper tire pressure and tread depth. Tires are the crucial point of contact between the vehicle and the road, so maintaining their optimal condition is essential for effective grip. Proper tire pressure ensures that the tires are neither overinflated nor underinflated, which can negatively impact their ability to adhere to the road surface. Correct tread depth is equally important: it allows for better water displacement, reducing the risk of hydroplaning, and provides the necessary friction on various road conditions.

While a smooth road surface does contribute to traction, it is not something a driver can control. Low vehicle weight and high engine performance also do not directly influence traction in the same way that tire condition does. Therefore, focusing on tire maintenance is the most effective way to ensure safety and performance while driving.
