Tire parts are essential components of a tire that help it to function properly. The two main parts of a tire are the TREADS and the RIMS. TREADS are the part of the tire that comes into contact with the road and provide traction. They are usually made of rubber and have grooves or patterns that help to increase the grip of the tire. RIMS are the metal rings that hold the tire in place and provide support. They are typically made of steel or aluminum and come in various sizes and shapes.
