In reponse to the story on tires:

<<
 
So-called "old" tires *do* harden. It's a chemical process, caused by
reacting with ozone and hastened by exposure to UV light. Generally, as
long as the tires are on the car and in use, you don't need to worry, as
the hardened tread wears off as fast as it forms. If you store tires, you
should:

- put them in sealed plastic bags, and
- store them in the dark.

If you do this, your tires should last for several years in storage.

Concur.  Rubber deteriorates with UV and is hastened by increase
temp.  Ideally, you would also want to keep them cool (in fact
high thread wear canvary by region in the US, highest in conrete
roads on hot climates).

YOu can also diminish if you can coat your tires with a UV [protectant,

I hear armor all does a job.
