WOT, but you don't say what year the Honda is. Weight is about 600 lb,
not 475 for most years.

That said, check tire pressure, low pressure in tires causes them to
heat up more, more heat leads to faster wear.

One of the folding 4' x8' kit trailers.   It had several
trips from S. Calif to Salt Lake City loaded to the gills
without this kind of wear.

Recently, been towing a honda CBR1000, about 475lbs.  3-4
thousand miles.  Major wear on tires.  ONLY change was
installation of oil filled hubs.
