Default DOT code tire age "sad story?"

Hi
i recently purchased a 1996 993.
seller told me that fronts were original, but rears were replaced ~ 10 months ago, ( he had sales receipt as evidence)

DOT codes as follows

Fronts = DBA 375

Rears = DBA 250

I'm interpreting that to mean;
Fronts manufactured 37th week of 1995.
Rears manufactured 25th week of 2000

Did he ,(and I ), get "ripped off" by him buying tires that had sat on the shelf for 6 1/2 years????????
or am i misinterpreting?

Bummer, cause the rears have ~ 800 miles on them and fronts = 18,000. all show nearly no wear / dry rot / cracking.

If this is true, i guess i'll be buying 4 tires, not just 2 fronts. :-(

be safe

Craig

Don't have time to check your results but here's another thread on this subject.
https://rennlist.com/forums/showthre...light=dot+tire

Personally I won't run tires over 7 years old and I took off all 4 tires on my '88 911 that had 75%+ tread because they were 10 yrs old when I got it.

Owners manual will tell you to never use tires over 6 years old on your Porsche.

can anyone verify my interpretation of DOT codes?

DOT codes as follows

Fronts = DBA 375

Rears = DBA 250

I'm interpreting that to mean;
Fronts manufactured 37th week of 1995.
Rears manufactured 25th week of 2000

Have a look at http://www.tirerack.com/tires/tirete....jsp?techid=33 and http://www.tirerack.com/tires-techpage-1/11.shtml Usually the date code is within an oval. Can you post photos?

Craig,
Mount up 4 new ones, from my experience the top of all the things not to cut corners on is the tires!

Was the PO local or close by? Put another way, where was the tire dealer located who sold tires well beyond the "sell-by" date? Might be worth a fone call at least.

the date codes are definately as i listed in the previous post. i was asking to confirm that DBA 375 = manufactured 37th week of 1995.
I've decided to face reality and accept that truth.

Both tire shop and seller are within 50 miles of me, i'm debating whether it's worth opening this can of worms.

I would not be inclined to raise the issue with the PO but I would with the tire shop. The result should be a smokin' deal on 4 new.

+!. Your odds of a positive outcome would be greatly enhanced if the PO was the one to take it in, or at least make the initial contact with the retailer.
