Why do all low profile tires have to be of high performance design?

Yes it is stiffer because it is shorter, my guess is that they make them thicker for rim/blowout protection. For things such as potholes. I had a 40 series Toyo go flat due to a nail once. I could hardly tell because the sidewalls were so stiff.
