Similar pattern to what I used way back.
After my noisy 33 X 12.5 X 15 Pro Trac tires wore out I replaced them with Sears Roadhandler ATs. They plowed great for me on my '77 Ramcharger and were not too loud over the road. I found an old add that can give you an idea of the tread design.
Far right in the picture. The LT next to it was more of a street tire and quieter.
