I could very well be wrong on that. Just a guess really. If they've spent their life indoors (warehouse) they might be OK.Do they feel soft or look like they are starting to brown anywhere?

PRE 2000 ID
In the example above:
DOT EJ8J DFM 408
40 Manufactured during the 40th week of the year
8   Manufactured during the 8th year of the decade

While the before 2000 Tire Identification Number format identified that a tire
was built in the 8th year of a decade, there was no universal identifier that confirmed which decade


After year 2000
In the example above:
DOT U2LL LMLR 5107
51  Manufactured during the 51st week of the year
07  Manufactured during 2007

This tire is WAY too old regardless of condition. Rubber breaks down with age. The life expectancy of a motorcyle tire is 6 years MAX

These are fo your car? Ok
when properly stored and cared for, most street tires have a useful life in service of between six to ten years.
Tires are manufactured by bonding rubber to fabric plies and steel cords. And despite the anti-aging ingredients
mixed into the rubber compounds, there is a realization that tires are perishable, & tires will actually age out before their treads will wear out.

For a car, this being said since these tires were made Sept of 2004. You can safely expect 2 years life out of them MAX. After that, swap em out.
