What age is this Tyre?

I'm guessing old.... I'm not familiar with this numbering system but these two are the only marks like it. They are on the brake side of the rear tyre.

Tyre is a Dunlop Elite Sport. Lots of tread but I think it's too old to ride on (even though the guy I got it from said it was quite new & he'd only put a few hundred miles on it... I have an idea it might be a take-off he got at a breakers yard... (salvage). :)

That looks more like a model or batch code from the manufacturer..the DOT code is usually in a oval with like 4 numbers in it.
 
If it has a date code, it will be after the DOT in the second pic.
 
If I remember rightly the sequence in the first pic follows the DOT in the 2nd pic....

If you look you can just about make out the "15" that is in white in both pics :)
 
Pretty sure it's from before date codes were used, so early nineties or older.
 
It's mighty old, that's for sure.

See if you can sell it on CrackList. :p
 
Date codes were in use back in the 70s.

Dan, at the top of the second picture I see the letters DOT. They should be followed by several numbers and/or letters, then a separate block that might have three or four numbers. That is the date code block. What is in that block?

.
 
Steve the second picture preceeds the first. So the only molded in markings that aren't a permanent (i.e. they have a border round them like this to signify a changeable block in the tyre mould tool) are these 2.

It reads:

41-23-41 DOT DA1X M23254

I'm wondering if the if it's an 84/94. Whatever at this stage it's kind of a non-issue it's exact date as I won't be riding on it or recommending that anyone else does... If it was from this century I may have put a couple thousand on it as my Avon is getting close to being done & I need to organise my wheel swap to get the next set on (I'm going to try Avon Azuro Radials) and have been a bit stuck for time.

:)
 
I found this if it helps to determine the date

Look at the date code for the tire on the sidewall (Dunlop HD example):

DOT DATR M2AM XXYY

XX = Week of manufacture
YY = Year of manufacture

DOT DATR M2AM 1607 = 16th week of 2007

Different brands may have the location of the DOT code, but its required to be on the tire by US law.

What's safer?...a 40 year Dunlop with no cracks or a 1 yr old Avon with cracks?:-k
One sticks great but wondering if it may split apart when scraping pegs and the other you never push into the corners because it doesn't hold anyway so who cares!
 
Who said my Avon is 1yr old with cracks...

Actually it was manufactured in late 2007, has about 9,000 miles on it & is just about done in the centre but is actually not quite on the wear marks yet.... :)

My 1000G had about 9,000 on the Avon on it when I last saw it but still had probably 30% of the tyre left. I think the Tubeless on the 1000G helps the running temps & thus the mileage.
