I wonder how much conditions have to do with tire longevity. I believe bias tires generally run at a lower pressure, have stiffer sidewalls and less flexing and run cool as long as they are adequately inflated. Radials are higher pressure, more flexing and generally run at higher temperatures due to the built in flexing. I would think those factors alone might cause more stress to tire components even if they are engineered for them. Combined with JW's comment about materials being selected and tires constructed for an easier recycle it could be a case of situations all coming together to provide a perceived shorter life for modern tires.
