Subject:      Tires: how to tell how old they are
Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes

Volks,

There is a growing amount of data about "TIRE AGING" that suggests we
should not use tires
   more than 6 years old.

The problem is called "thermo-oxidative degradation".

In fact the data on tire aging is so compelling that most car
manufacturers now include a
  statement in their owners manuals.

In fact VW was one of the first to do this.

Example from 2000-2001 Volkswagon Golf Owner's Manual:

"WARNING -Tires age even if they are not being used. Tires which are
more
than 6 years old should be used only in an emergency and then with
caution."
"WARNING - Old tires can fail in use, causing loss of vehicle control
and
personal injury. Replace tires after six years regardless of tread
wear. Always
reduce speed and drive cautiously if you must use an old tire in an
emergency.
Replace the tire as soon as possible."

But how do we tell the age of our tires?

Here's how:

Knowing how to read the date code on your tire may not only keep you
safer on the road, it might
also keep you from buying a new set of tires that could be several
years old before you put them on
your Bus.

In the link above you will see a few examples of stores selling tires
several years old as new.

Maggie & I cruised the local Sears Auto Center this morning. We found
new tires on the sales floor
  ranging from 2004 to 2008.

Something to think about  ... be an informed consumer.

If you are interested in other info about choosing a proper tire for a
Vanagon, here's a
perspective.

Note ... if you go to the above link it will be our secret .

  I will not out you to the rest of our community as an "Informed tire
consumer".
