The current letter load rating system for radial tires replaced load ratings based on the number of sidewall plies used for bias ply tires.

Between the two systems was an interim system where radial tires now designated as "E" load rated were referred to as "10 ply rated," although that did not reflect the actual number of sidewall plies in radial tires. What are now "D" load rated tires were called "8 ply rated" and "C" load rated tires were called "6 ply rated."

The tire in the photo above has 2-ply sidewalls, which is not uncommon in both D and E load range LT radial tires.

thanks, so how would this compare with a BFG A/T KO2? Do they also have 2 ply sidewalls?

You can look up the specifications for most tires on the manufacturers' websites. Some include the number of sidewall plies, some don't.

Today's sidewalls will be 2 or 3 ply, but the thickness and strength of each ply is also a factor. For example, Duratracs have 2 plies and have been criticized on this forum for getting sidewall punctures easily, while Falken Wildpeak AT3W also have two plies but have been reported to have good sidewall strength. Some Nittos have 3 plies and are reportedly strong. . .

Yep. The tire I've seen fail most often is the BFG KO/KO2...which of course have 3 ply sidewalls. So there is more to a sidewall than the shear number of plies. Thickness and strength is most important.
