The Carlisle 5.30-12 tire and the Loadstar 5.30-12 Tire, # AM30850, are very similar. They are the same size and have the same load range rating (load range C). A tire with a C load range should have a ply rating of 6. So in size, load range, and ply rating, they have the same specifications.

A tire can have a 6-ply rating (load range C) and not necessarily have 6 plies listed on the sidewall of the tire. The ply ratings were introduced when tires used cotton layers to strengthen a tire casing and used 6 layers. Today, with new materials, when tires are labeled 6-ply, they do not actually have 6 layers, but will have the equivalent strength of 6-plies, called 6-ply rating (load range C).
