Amazon's hand-truck tires seem to be 10-inch 3.50/4.10-4 (4 ply). One
says it's good for 50 PSI.
The weak point may be the rim. I've read of a recall by one brand of
truck because the rims may bust and hurt somebody if you put in more
than 30 PSI without installing a fixit kit.
I imagine 15 PSI would suit me. I wouldn't want my goldfish to slosh
out of the bowl on bumps!
My understanding is that some truck tire rims (so called "split rims")
consist of two or more pieces, but are press fit together so they look
like a single piece of steel. Inflating those tires can be very
dangerous because if overinflated, the two pieces of the rim can
separate with such force that the flying pieces of the rim can kill a
person. But, these "split rims" are only used on the tires of fairly
large trucks, never on car tires and certainly not on the small tires
you find on a hand truck.
Many of the tires used on airplanes have these press fit "split rims",
and about 20 years ago someone at the Winnipeg Airport was killed when
the airplane tire they were inflating came apart with such force that
the flying piece of rim took the airport employee's head right off.
You can still claim that distinction , as several others have said the
info you want is easily found on the internet , And I haven't seen a tire
yet that didn't have information such as size , max load @ pressure ,
manufacturer , etc molded into the side wall . Maybe you need glasses - or
yours checked . Oh , wait ! You're blind , and they don't mold that info on
tires in braille !
I have one too , and use it for a dead end spam trap . I might check it
once every six months or so . I post to usenet thru a news server using a
newsreader . My point was that both ggmail users and googroupies are losers
that can't figure out a simple usenet interface . Hell , I'm an old dog ,
and I'm still learning new tricks . My wife taught me to "roll over" last
