I know nothing about trailer tires, but I'll be pulling our little 1974
Ladybug brand utility trailer behind Mellow Yellow to Bend, lightly loaded
with stuff and I want to make sure the tires are aired appropriately.

Here's a picture of the trailer.

I included the Bentley's manual in the shot so the size of the trailer can
be judged -- it's little. Doesn't weight much, either. Fiberglass body,
simple steel frame. Re-did the wiring, brought it up to CA code. Added a
backup light, too.

Anyway, the tires are only a couple of years old and are labeled:

Deestone (whoever that is)
ST175/80D13 (replaces B78-13ST)
TRAILER SERVICE
6 G.P. Load Range
Max Load 1350lbs at 50 p.s.i. cold
Nylon cord

So . . . 45psi sound about right?
