Trick to getting the tube out of the tire?

There must be a trick to getting the tube out of the tire after taking off one side of the tire correct? Or do we need to dismount the entire tire from the rim? 30 by 3 1/2 demountable.

No trick really Dan...
Just hold the tire open and pull the tube out.
May be more difficult on a old hard tire.

I push the valve stem one way or the other so it's parallel with the rims... same installing (helps to have thin fingers and be impervious to pain), otherwise the valve stem makes it tricky.
I've been told tire flaps make it easier, but I've never been good at using flaps without pinching tubes...

So you just take of one side of the tire and pull the tube out? Easier said than done, mine wont budge, but will keep trying, could not imagine how much more difficult it would be with the metal stems, mine are rubber but still nearly impossible. I think I will let it set in the sun for an hour and see if that will make it easier.

Your tire doesnt have flaps in it does it? Cause they really make it a b---h to pull the tube out!

I found the culprit to be that the tube stem had cut into the rim which was the reason it went flat to begin with. I think from now on, I will use metal stem tubes. I suspect others have had this same issue. Thanks

Cuts in the stem almost always come from under inflation. I run both metal stems and rubber stems on my cars and have never had a problem with either style stem. I run 60 pounds in the front and 70 in the rear on my clinchers. I use flaps and have found that removing the tube is easier if you break the bead in the back of the tire too.

Thats why I tell people "20 PSI PER INCH WIDTH!!!"
People think they're running balloon tires, and they NEED that high pressure to keep their tires anchored to the rim.
Under-inflation causes tube stem failures... among other problems. If you're not running 70 in your 30x3.5's (or 45 in your balloons) you're asking for trouble. They knew this back when our cars were transportation, not speedster runners and tour queens - don't second-guess those who lived back then and relied on these cars as their daily drivers.
Sure, everyone likes a squishy, soft ride, but it's not what these tires are made for. They're the halfway point between straight side tires (eg semi-modern) and Hard Rubber. If you have a car from the era... it's NOT a modern car. If you want a soft ride - well, a T ain't it.

Ford recommended 55 psi in clincher tires and 27-30 psi in balloon tires. Here is the chart from a 1926 owners manual:
