Am I looking at the wrong DOT code??
If not, what does the letters mean?

Hey Roger, check the other sidewall. The whole code will be there. The side you need to read, almost always get mounted on the inside, to make you crawl under the trailer/vehicle.
All of the letters are manufacture codes, which when decoded, tell the size, ply, size, etc of the tire. The first two (OH in your case is most likely the number zeroH, as the letters O,I, and Z are usually not used because they look like numbers, but they be running short of two digit combinations)) always tell what tire plant produced the tires. I'll check tomorrow with my book at the shop to see who made it.
