Tires/Tire age


Can you tell what decade this tire was made in?  It's a Goodyear S4S,and the numbers are:  DOT M6UL H1HR 499



Is there an arrowhead near the date code 499?  An arrowhead will look like this <|  If so, then the tire was produced in 1999.  

If not, then the date code is no help.  And the tire name is only of some help.  I remember Goodyear S4S's as being fairly recent, and not from the 1980's or earlier.  

So best guess is 1999.

I have over 30 years experience in the design, manufacturing, and testing of tires. I have served as the technical advisor to the "800" number. I have authored or co-authored many publications - usually without credit. I can answer almost any technical question, but please don`t ask me to compare brands. I probably have prejudices because of my work experience.
