Either would work but if you can find a wider (700 35~45)
tube it would be better as it will not stretch as thinly to
fill your wider tire. At any rate be sure to find the cause
and correct the problem before fitting a new tube.

Thanks for the response.

Flat tube when pumped up was leaking out of a patch : ) I did not see any
damage to the tire inside or out where the patch occurred and the rim appeared smooth.

The schrader/ presta fix I was referring to is here. Do you have any opinion? TIA.

Going with the concept that the simplest solution is usually the correct
one, I would say to buy the type of tire made for the type of rim that you
have. In this case a Schraeder valve. Why would you be limited to what is
available at Wal-Mart? A local bike shop sounds like your best bet and in
addition to finding you a tube, they should be able to answer your
questions.

I see no value in trying to get a presto tube to work in a rim made for a
schraeder tube. Seems like just asking for trouble.

I did it, for the same reason that the O.P wants to change from Presta
to Schraeder. I didn't have a pump to fit Schraeder valves.

What I did was turn up a couple of shouldered washers to fit the
larger Schraeder holes although it probably was over kill. A couple of
years so far with no problems.
