Re: Do tires have date codes?
I think you may be missing part of the number, look on the other side and see if there is one that is longer...it should look something like hyhl 380 1606. Of coarse depending on how old the tire is on the amount of digits. HYHL is the plant code. 380 is the tire model and 1606 is the 16th week of 2006. If the last digest would have beed 166 and have a triangle beside the last six, that is a decade market, which is used every other decade. The triangles were last used in the 1990's. Anthing over five years, in my opinion should not be used. The Rubber manufacture association (RMA) says that rubber is good for 10 years, but I have seen way to many cracked up and failed tires do to age....better safe then sorry.
