Ok this photo shows what started the bumps, the casing was cut from the out side by a puncture that would have left any one else with a flat tire and a hopelessly chewed up tube.
I am going to start gluing tire treads on the road side of the high pressure tires I use. The 2.25” moped tire at 35 psi can't do as well as three tire treads per wheel.
Obviously that is too much weight for most people, so I can expect the tire industry to ignore what I want. Or even send in a professional agitator to repudiate my tire odyssey.
