age issues, not mileage

[roger crabtree <rcrabshish@xxxxxxxxxxxx>]

Hi list,  
My 2 cents on this subject is rather scary.  Some are
saying that 4 years is along time on a car, no matter
what the mileage.  The question is how long have these
tires sat in the factory?  How long at the dealer? 
Some tire shops will brand their own tires.  Could
this be the problem for some companies like Firestone?
 I know a tire that sits a lot will have more problems
than one that is driven.  Sunlight is also a large
factor.  Then as a very heavy car "Imperial" driver, I
need to look at load range.  In our state the roads
are not the best.  Road temperatures are also a very
large factor.  This is proven on the freeway by the
large amounts of rubber left from truck blowouts. 
They increase with the temperature.  I chose to buy a
good tire.  One that I have had good luck with in the
past.  New tires by certain companies are not always
the best.  My Pt had Goodyears on it.  They lasted
about 16,000 miles.  I will never buy a Goodyear
again.  I guess the moral to the story is this.  We
must alway expect Murphy's law to come into effect. 
If it can happen odds are it has.
