I found a set of used RA1's with lots of tread remaining (4/32), but need help figuring out the production date. The codes are:
2L1239 &
2L1459

The most recent thread on RA1's refers to a week/year code, but 12th week, 39 year?? Are they possibly very old?

Look on the other side of the tire. The one side has the first portion of the DOT that identifies the plant where it was manufactured and also what tire it is. The other side has the full DOT.

Thanks guys. From the link, it looks like they were both manufactured in 1999. That makes them past their usable life I'm guessing...unless 1999 was a really good year for tires!

10 year old track tires are junk even if they've never been used before.

I just bought a set of 225/45/15 RA-1s from racetire.com. Their build date is the 30th week of 2006 [Frown] Are many of the newly purchased RA-1s this old?

All the RA1's that I have are from 2009.

Return em, ask for newer ones. Or ask for money off. NItto just practically gave away something like 100 sets of their NTo1 because they were an 05 build date.
