PR is an abbreviation of "ply rating". This label originally indicated the number of layers of cotton fishing line in the shell. A large number of bearings means a higher load capacity. When stronger materials were introduced for bearings, this term was removed from the actual number of bearings. Currently, a tire with 8 PR can only have four nylon linear bearings. Today, the stability of a controlled tire is expressed in terms of load capacity and speed capacity, and not in terms of the ply rating.
AT 621 is suitable for backhoe loaders and compact loaders in all farming digging and loading operations. The AT 621 tire features an extra deep tread which ensures great cut resistance and higher durability. AT 621 is available in several versions to meet the most differing user requirements.
