Read an article about aging tires and how they may be related to car accidents.

So I went out and got the manufacturer date off the tire, here are my results:

GoodYear Wrangler Authority (bought as a set from Wally World)
XXXX, First 2 numbers are production Week, last two are production Year.

21st week of 2011
16th week of 2010
16th week of 2010

Odd ball Goodyear Wrangler:
38th week of 2013

So my odd ball is the newest tire I have....

Pics of the date code:

 

Yep, good to always look at the tires before purchasing to make sure they aren't leftovers. Recommended lifespan is around 4-5 years regardless of wear. I just purchased new tires recently and made sure they were all 2014 and I also replaced the original Michelin spare even though it looked fine.

 

My BFG's are all 2410... they've been on since Nov 2011, so they where in transit/on the shelf for 17 months... I have over 38k on them, and they're not even half done yet... got ~86k out of the first set... the sad factory Goodyear's only made 44k.

 

my grabber at2s are only a few months old... id have to double check the date, but they were made only a couple weeks before i bought them.

 

i bought used firestones 2 years ago, and last week i found cracks along the sidewall and along where the tire meets the rim... who needs new tires? THIS GUY!
