Actually, Hillrider did say that just above. And that's worth repeating. In my case, the tires had perfect casings, even the skinwalls showed no signs at all of checking. The only evidence of age was the splitting of the black rubber, and only at the center seam. Had there been any sign of weakness or degradation of the casings on any part of the tire, I would've tossed them for sure.
