Ply Rating (PR)

What is Ply Rating (PR)?

Ply Rating (PR) is A method used to indicate relative tire strength, formerly used to designate the load-carrying capacity of a tire. The ply rating does not necessarily indicate the actual number of plies; a four-ply rated tire, for example, may have two plies but is considered as strong as a standard four-ply tire.
