Yep, these are pretty beefy for such a little trailer. I know what you
were thinking of: those little donut tires that one finds on Harbor
Freight and similar trailers. I forget the size of the tires that were
originally on it except that they used a size and size designation that is
no longer in use these days. So I found the closest contemporary tire with
similar o.d. and width, and found wheels with the same bolt pattern. In
other words, these tires are very very close in size to the original ones,
and pretty similar in terms of load rating.

I'm not super familiar with truck stops and scales places, I'll keep an
eye out for something suitable. I'll be heading north on I-5, the truck
traffic is super heavy. I'll bet that Al Knoll might know of a place.

Heck, I doubt the trailer and payload will weight more than 500 lbs
combined. That's 250 lbs per tire. That's too light to be on the chart. I
presume that less than 15 psi would be silly.
