I'm not sure of the dates, but somewhere back in that time frame, TM used 13-inch tires on their trailers. If your TM is one of these, you can think about upgrading to 14-inch tires, but TrailManor, and many of us owners, have gone to 15-inch tires in the last couple years. I have no idea if either of these upgrades from 13-inch would require a new axle. The 14-inch to 15-inch upgrade did not.
