I just received my Hagerty Magazine in the mail last week (Spring 2014 Issue)
In the Q&A (Question and Answer page 62) a guy asks about "shelf Life" of Tires.
The Answer was: "tires are rubber based, and rubber deteriorates" it goes on to say "experts consulted suggest
Tires should be replaced every 5-7 years, and that goes for Classics as well as modern Tires".
I think the experts are either rich or getting kick back for their opinion, because I have driven on Tires that have
been 10 years old and older with no problems, for decades. The Answer does wind up saying "Tires are sold (After 2000)
with a 4-Digit code on them". "For Instance, a Tire coded 3303 was manufactured during the 33rd week of 2003".
So I at least learned something from reading the magazine - not the throw out your tires every 5-7 years thing,
but the coded part - L.O.L. Who's got a Grand for New Tires every 5 years? Maybe Jay Leno.
