Structure Of R Tire

R tires, also known as radial tires, have a complex structure consisting of several layers of different materials that work together to provide a comfortable ride, good traction, and long-lasting tread life. Here is a breakdown of the structure of an R tire:

• Tread: The tread is the outermost layer of the tire that comes into contact with the road. It is made of a durable rubber compound that provides good traction and resistance to wear. The tread pattern can vary depending on the intended use of the tire, with some patterns designed for improved wet traction, snow traction, or high-speed stability.
• Belt: The belt is a layer of steel or synthetic cords that sits beneath the tread and provides reinforcement and stability to the tire. The belt helps to prevent the tire from expanding under the centrifugal force generated by high-speed driving, which can cause the tire to deform and lose its shape.
• Ply: The ply is a layer of fabric cords that runs from bead to bead and provides the tire with its strength and flexibility. The ply is typically made of polyester, nylon, or rayon and is coated with rubber to provide adhesion between the layers. The number of plies can vary depending on the size and load capacity of the tire.
• Bead: The bead is the part of the tire that sits on the rim and provides a secure attachment between the tire and the wheel. The bead is made of steel wires that are coated in rubber to provide flexibility and grip.
• Sidewall: The sidewall is the part of the tire that connects the tread to the bead. It provides protection against impacts and helps to absorb shocks and vibrations. The sidewall is also where the tire’s size, speed rating, and other information are printed.
