If you're talking about a bulge of like a quarter inch or so, that's pretty much normal. The flap will keep the tube inside where it belongs, assuming the flaps weren't incredibly thin and flimsy. Some tubes will come with a metal washer built in around the valve stem but there are no plates used to cover the valve stem cut-out in the wheel.

I don't know if you need 110 psi though, unless you're always lifting max load and the front end drops when you lift a load. I have a bunch of Hysters with dual 700-12s and I like to keep them around 90 psi max. They wear out in the center even at 90.
