When I purchased my FW new, I noticed the tire sticker on the trailer did not match the brochure info, or the tires installed. The sticker said 235/80 16D, and the tires installed were 225/75 15D.
I called the factory with the vin, and they said it was ordered with, and left with 225/75 15. They also offered to send a new label.
I had looked at two other FWs identical to mine, both of which had the same 225/75 15D. One had the correct sticker for the tires, and the other like mine was wrong.
Tires do fit the trailer specs as installed.
