had the same problem with tubeless dolly tires going flat. Inserting a
tube
is the only thing that fixed it.

I tried getting the tire to bead against the rim with rope and bouncing.
Didn't have any luck. Without a high pressure pump is seems useless.

May try a tire place. Maybe they'll fix it cheap. Would rather go with
tubes. I noticed there are numbers inscribed on the sidewall. Maybe the
Internet or small engine repair shop will have them.

I'm curious where did you get your tubes?


I have a Home Depot type of dolly that has a flat tire. Tried pumping air
into the valve... couldn't get any pressure in the tire. Doesn't seem to
have any nails in it. Couldn't see any tube inside either. Reminds me of
a regular car tire.
I know it sounds silly, but I thought of bringing it down to a tire shop
and having them look at it. Or, would I be better off taking off the
wheel and buying a new wheel/tire unit?

The tire thickness and wheel build is similar to that of a regular car
tire. Get the feeling I would need a special machine to take it off and
put it back on again.
