That's partially true, I did an engineering report a little over a year ago
on failure modes of a tire, there are actually very few: Impact puncture,
delamination failure (firestone) [caused either by heat build up from over
loading or improper inflation pressure or both or tire construction
engineering {poor vulcanizing process}], main body cord separation, and
mechanical wear (just plain worn out). In the course of my research I
learned some interesting things. One, tires actually benefit from being
driven on, they seep out oils and waxed that fend off dry rotting and Ozone
damage as the sidewall goes thru it's loading-unloading cycles. Certain
chemicals can actually prevent this from happening, Armorall is one of them,
a tire actually becomes dependent on armorall. A tire can be stored
indefinitely without damage if it is stored properly, it must be stored in an
area free of excessive humidity or temperature extremes, also it must be kept
away from electric motors, they emit an ozone gas as they operate which
decomposes the tire, tires also need to be kept out of direct sunlight, they
should be stacked on edge not on the tread, barrel stacked if you will.
Anywho, speaking of engineering I have a lab to be at in 45 min, so I must be
going. Just thought I'd share.
