Which type of tire tread orientation involves plies running in different directions?

Bias Ply tires are characterized by plies that run in different directions, typically at angles of around 30 degrees to the centerline of the tread. This construction absorbs shock and provides a flexible sidewall, which can make them suitable for certain applications, particularly in off-road scenarios or where maximum traction is needed, such as in agricultural vehicles.

The angled construction allows for increased durability and helps improve load-carrying capacity. In contrast, Radial Ply tires feature plies running perpendicularly to the direction of travel, which enhances fuel efficiency and offers improved handling at higher speeds due to the stiffer sidewalls. Flat Ply and All Weather tires refer to other specific tire types and characteristics that do not align with the unique design of Bias Ply tires.
