[s-cars] Tire Shelf Life

[John Cody Forbes]

Here's some info I found:
The British Rubber Manufacturers Association (BRMA) recommended practice 
issued June, 2001, states "BRMA members strongly recommend that unused tyres 
should not be put into service if they are over six years old and that all 
tyres should be replaced ten years from the date of their manufacture."

More recently, The Japan Automobile Tire Manufacturers Association (JATMA) 
recommended practice issued May, 2005, states "customers are encouraged to 
have their vehicle tires promptly inspected after five years of use to 
determine if the tires can continue to be used (recommends spare tires be 
inspected as well). Furthermore, even when the tires look usable, it is 
recommended that all tires (including spare tires) that were made more than 
ten years ago be replaced with new tires."

While American driving conditions don't include the high-speed challenges of 
the German Autobahn, Chrysler and Ford Motor Company joined their European 
colleagues in 2005 by recommending that tires installed as Original 
Equipment be replaced after six years of service."


Personally, I've typically recommended not mounting a tire that is more than 
5 years old, but I've never recommended removing a tire purely by age (only 
by condition).

For an anecdote related to this, my father and I are showing one of his 
914-6's in a Concours next month. It's a 1970 914-6 with about 5,000 miles 
on it and still on it's original tires which are in remarkably good shape. 
Part of the Concours involves a short drive. We are pretty sure we will sit 
out the drive, but have been joking about if we do the drive we would have 
to use other wheels and tires, but that would be a shame since it's very 
likely that the lug bolts have never been loosened since installed at the 
factory!

That's a bit on the old side IMHO.
