Extra wide tires are designed with a larger contact patch, which means they have a broader surface area that touches the ground. This feature enhances grip and stability, making them ideal for vehicles that require better traction, such as off-road vehicles and sports cars. They can improve handling and performance, especially in challenging driving conditions. These tires can also provide a smoother ride by absorbing more road imperfections. However, they may lead to increased rolling resistance, which can affect fuel efficiency. Additionally, extra wide tires can alter a vehicle's appearance, giving it a more aggressive stance on the road.
