What is ply rating, what is its significance, and how is it different from ply?
Tires are generally constructed using plies or layers of material. This constitutes the physical Ply construction. Typically, the more plies used in the construction makes the tire more durable and gives it more load carrying capacity. Ply Rating is a numerical rating given to a tire, and is based on the load carrying capacity of the tire. So a 2 Ply tire can have a 2, 4 or 6 Ply Rating depending on materials used, shape & other construction aspects. The higher the Ply Rating number the more load carrying capacity the tire has.
