6. Sometimes a tire that appears to be fine may be unsafe because: A. There may be perforations too small to see B. The manufacturing date may be incorrect C. Chemical reactions may have deteriorated the rubber

C. Chemical reactions may have deteriorated the rubber

Explanation:

A tire ages with time and most of the time this happens due to chemical reactions in the rubber parts. This could happen faster due to heat and sun.

As a tire is deteriorating or aging, a chemical change happens. What happens is that more chemical bonds are going to be produced with time between the molecules. We call this the process of oxidation. This actually bad for the tire, because the rubber would turn out to be stuffs d strong causing the tires thread to separate and also disintegration would occur.
