[Shotimes] (OT) Safety group seeks tire expiration date

Ron,

I did acknowledge that old tires fail, but probably not at a 
rate a lot higher than new tires. I didn't read so well on 
another topic earlier (shims/valve stems clearance) and you 
missed this one....maybe us old farts just can't read anymore?

Being involved with the old car hobby like I am, old tires 
are just not a big concern of the group as a whole.  I think 
most people in the hobby understand that the older a tire 
gets, the less you should trust it, but I have had FAR more 
new or nearly new tires (about 3) fail on me than old tires 
(none).

I think replacing tires every two years is way too soon, but 
it is your money.

Heck, the RACE tires on my '89 are now getting to be about 
eight years old, and they see lots of high speed and stress. 
  I think I will retire them this winter though, may have 
pushed my luck enough, especially since one of them has a plug!

If those GTII's on the Fiero are still in good cosmetic 
shape, you might want to keep them and sell them on E-bay. 
Someone will want them for SHOW purposes I am sure!

:)
