Defining Bias Ply and Radial Tires

Bias ply tires have a construction that consists of multiple layers of rubberized fabric cords. These cords are placed diagonally across the tire, forming a crisscross pattern. The layers of cords are then coated with rubber to create a strong and flexible tire.

Bias ply tires have a durable and robust construction, making them well-suited for off-road and heavy-duty applications.

Radial tires, on the other hand, have a different construction that features layers of cords positioned radially from the center of the tire to the sidewall. These cords are made of steel or polyester and are placed at a 90-degree angle to the direction of travel.

Radial tires provide excellent stability and handling characteristics, making them popular for highway driving.

Historical Development of Tires

The development of tires can be traced back to ancient civilizations where primitive forms of wheels were utilized. However, it wasn’t until the late 19th century that the pneumatic tire, or air-filled tire, was invented. John Boyd Dunlop is credited with the creation of the first practical pneumatic tire in 1888.
