Physically process of tire aging can be described as the collapse of the molecules, as well as the formation of new intermolecular bonds in the process of oxidation. But in addition the temperature factor effects on aging tires as, namely, the thermal decomposition of rubber at high temperatures. From this point of view, the temperature conditions regains crucial to use rubber as rubber tires required density is maintained only within a certain temperature range. Factors that influence the aging of the rubber should also include the interaction with chemical compounds from the external environment, because of which the tires lose their elasticity, become harden, causing the appearance of age cracks and other signs of aging.
Such rubber aging traces may prevent full adhesion. Careful inspection of the tires on the subject of aging is still best left to a specialist who can answer your questions, is further tire operation possible.
