Hi, all... I recently had a mysterious flat, and decided to get a single used replacement identical to the other tires on my coach. All the tires are about 6 years old, so I'm not planning on running them TOO much longer (hoping to wear them out first). 
Thing is, the used tire showed up with a couple issues. On the bright side, it was almost totally unused - it still had the factory paint between the treads, so it couldn't have rolled more than a few miles. OTOH, it had a nail in it that the vendor had missed (easily and permanently patched by my favorite local tire store), and second, it had a 2002 manufacturing date code. Otherwise, it looks virtually new - not a weathercheck on it anywhere... the rubber is dark, supple and shiny.
I was in a bind, had a trip to do (and a good, though also old spare on board), so I mounted it and ran the tire up to the Grand Canyon and back (about 400 miles round trip).
The Ebay vendor has offered a partial refund (TBD) or to send me out a tag to return the tire.
What would you do if you were in my shoes (tires)?

If you buy lotto tickets...keep it cause you're a gamblin' man . If you
never buy them, send it back..
Just what I would do. Oh and if the former, have you won much :)

Personally, I wouldn't run on a 13-year-old tire. I'd send it back. I've seen the results of old tire blowouts on RVs (no GMCs as of yet), and it ain't pretty.
I just replaced mine, and they were "only" 10 years old.

Based on my experience an old tire is an old tire even if it is unused. Around 1995 I imported about 200 Kumho tires to fit vintage Honda Cars and Mini Coopers as the 10 inch size tire had become unavailable through normal distributors. The new Tires worked great No problem but after about 8-10 years or so a few of the "new" old stock (NOS) tires, when used, started having tread separations and blow outs even though they were stored inside and each warped. Had the same problems with NOS Michelin tires when you could find them in that size. In the case of the Michelins the side wall gave out.

I go with the 10 year old rule rule on RV tires as published stated by Michelin. I just a week ago replaced a 13 year old Michelin "spare" tire that had never been on the ground and had spent it's life covered on the back of my coach.
Let's face it. Even though Michelin recommends a 10 year life on RV tires, they are not going to magically explode in the 11th year. You know they left themselves some wiggle room in their published recommendation. Still I feel 10 years or so is a good time to replace them.
So the 13 year old tire no matter how well it was previously stored in my opinion ought to go.
I have never blown a tire on any vehicle and I own lots of older vehicles, but but you need to set the bar somewhere. My newest vehicle (a truck) is 10 years old 100,000+ miles and probably ready for new tires this year. I have Blazers at 16 and 17 years old that have had several sets of new tires in their life.
So run them until they wear out or around 10 years old.

Hmmmm.. I know this 10yr rule is good..... but my 64 vette got its last new tires around 1976..... But it IS on its 6th free lifetime JC Penny replacement since 1971....
New GMC tires around 1995. Guess I better think about new ones for it tho.
Thanks for the reminder!

Thanks for all the input, folks... it's good to get a second (and third, and fourth, and fifth, and...) opinion.
I'm kinda where Ken is on this... I agree that a lot of six year old tires are really done, mainly those that have been left out in the elements for long periods of time. OTOH, there are guys like Mike Kilroy running tires that are old enough to vote and getting away with it.
The other six year old tires on my coach spent half their life inside in California, and most of the time in Arizona inside (along with about a year under cover). None of them show any weatherchecking at all, though I did have those two odd failures (I put up some photos on another thread). I'm convinced that those failures had nothing to do with age, but something that got on the tires and "dissolved" the rubber (if you look at the photos closely, you can see where the lettering in the area of the discoloration got "blurry").
I guess in the end, my to-do list includes...
1) Replace that 13 year old tire with something a whole lot newer
2) Start thinking about six new tires, though I'm not going to get my knickers in too tight a twist over it quite yet...

On that particular tire I'd be more concerned about what the nail severed in terms of critical fibres. There is no way of knowing the structural integrity. For me no nail patch job on heavy vehicles.

One more opinion. I asked my buddy engineer in Akron area, who I have
worked with for 40 yrs, who has during this whole time worked for us,
then himself as consultant to, Goodyear, Goodrich, and then the Japanese
mfgrs as they bought up our American tire companies there. We have
signed many non-disclosure agreements with them over these years. I
would say he has a fair opinion of tire life based on how they are
manufactured. You may not want to know that a typical tire has about $
5.00 worth of purchased material in it....
He replied to my questions:
Ok let's keep it short answer.
UV kills tires (and almost anything else) so indoor storage really helps.
Reasonable temperature excursions don't matter too much, so unheated
barn/garage doesn't do much harm.
So now for the biggies: was the tire relatively unworn when put into
"storage"- a tire, say half worn out or more-will die faster under
storage conditions. was the tire inflated and subjected to supporting
the vehicle weight? That hurts life. Was the tire deflated and subjected
to the vehicle weight? That pretty much kills the tire after a few months.
So now we need to define what we plan on doing with the old tire. If it
was unloaded etc it's good for many years (10+) but not at high speed on
a 'vette". If it was loaded but not seriously deflated it's good for
several years (4-5).
Creatures gnawing on the tire really hurts. Ha ha.
Follow up question brought:
Keep them round and they avoid the usual failure modes (ply separation
belt stretch etc ) and are good for a long time. Drive the vette like
the motor home and don't worry. All will be well.
