Aw, gee. Some tires are just on the small side of spec, and some rims are on the big side, and when you put 'em together it's a struggle. Especially for those of us with tired thumbs.
Here's a tip, though. After seating the first bead starting at the valve stem, start the second one opposite the stem and finish at the stem. You'll have more bead in the center of the channel, making it a bit looser for that final pop. Remember to push the stem in the hole to make sure the tube is seated.
