The "D" on a trailer tire stands for "Diagonal," referring to the tire's bias ply construction. This means the layers of the tire are arranged in a crisscross pattern. This information was found on the "Tire Tech Information - Trailer Tires vs. Passenger Vehicle Tires" page of Tire Rack's website, specifically in the section "Tire Size and Load Range."
