When are rib tread tires preferred over lug tread tires?

Rib tread tires are preferred on highways primarily because they are designed to provide better fuel efficiency and a smoother ride on paved surfaces. The continuous rib design of these tires helps to reduce rolling resistance, which can lead to improved fuel economy. They also create less road noise and improve handling on well-maintained asphalt. In contrast, lug tread tires, which have deeper grooves and protrusions, are more suitable for off-road or rugged terrain where greater traction is needed, such as in mud or snow. Therefore, the application of rib tread tires on highways is ideal for maximizing efficiency and providing a stable driving experience.
