Thank you guys. The rim tape is BBB also. It feels plasticky
"It was so tight that even with just one bead in the center, no tube yet, I couldn't slide the tire around to line up the label with the valve hole. That's tight!" Yep that sounds exactly like my current setup. Your post with the pictures is very helpful, I will employ that technique next time
I just didn't know how to push the tube in...the tire was just a flat ribbon sticking out 90deg from the rim
