I feel the whole rubber thing falls under two catagories...
1. Cheaper materials.
2. Increasing U.V.
scientists analyzing 30 years of satellite data have found that the amount of ultraviolet (UV) radiation reaching Earth's surface has increased markedly over the last three decades.
The primary culprit: "decreasing levels of stratospheric ozone, a colorless gas that acts as Earth’s natural sunscreen by shielding the surface from damaging UV radiation."
That pesky hole in the ozone layer cropped its head back up again?
How does that explain why the tires rot when in storage and all the hoses rot under the hood of my truck so quickly?
What's funny..I've seen OEM hoses from 1956 be perfectly serviceable. While replacement hoses start rotting within 12 months many times.
