G-Y Eagle ST age?

Don't remember exactly what model tires they were but I had goodyear eagles on My Cop wheels when I bought them. finally went and got new tires a while back the saleman cringed told Me those tires were 10 years old at least.There's a code on all tires if you know how to read it it will tell you the production date .Hope that helps .I don't skimp on tires they're the only thing between you and the road !:toothy10:
