The folding bead is lighter, but it doesn't change the flex of the tire, since it lies against the (ultra-stiff) rim.
What makes a tire supple is: 1. Casing construction. Finer threads, less rubber, etc., all make the tire more supple. Puncture-proof belts make it less supple. 2. Tread thickness. Thinner is more supple. 2. How far the tread rubber wraps around the tire. The tread rubber stiffens the casing, so the less you wrap it around, the more supple the tire. Of course, all these factors need to be balanced so that you get a tire that works in the real world. Different conditions require different tires...
