I just finished mounting 5 new Goodyears by hand. First tires ever hand mounted. The trash bag method worked fine. The guys here were very helpful. SEARCH: Trash bag. U-tube has several hits with video, also motorcycle tires similar.
I learned: If pushing tire on rim with palms of hands, wear gloves! My blisters should be healed in another 4-5 days.
Setting rim outside down on 4 padded 2x4 pieces helped.
Feet with sneakers worked better than hands.
Bead of tire must fit down into rim center. You aren't trying to stretch bead over rim, just slide it over rim (trash bag inner talc aids this)
Corn-starch ($1.38 Walmart baby powder) helps a lot to get tube to slide into position in tire, prevent rubbing.
One rim required duct tape around inside, then rim strip to prevent tube rubbing on pitted areas.
Slightly airing tube before inserting helps prevent pinching tube.
Go for it, these guys even taught me how to do it.
Dyna beads next.
