There's actually such a thing as "2 ply tires" for use on motor vehicles???
The # of plys varies by manufacturer and design and isn't directly comparable to load rating anymore. Here is what Goodyear says of the SR-A construction:
The tire's internal structure includes twin, high-tensile steel belts on top of a polyester cord casing. Heavy-duty LT-metric-sized Load Range D & Load Range E tires are reinforced with spirally wound nylon to promote strength, even wear and extra durability.
