In my never ending travels, I'm in Indiana now, going east to Baltimore, Md. I have two windrowers (they make rows of hay for balers to bale) going to Russia. I added a pic for you to see. Their drive tires are off for ease of shipment, yet they are still 12 feet wide. If you are wondering, my trailer is 102 inches or 8 and a half feet wide, and a regular interstate lane is 12 feet wide.
