How do you tell the age of a tire with serial # 31LL7842. It is a 4.75-5.00x18 Kelly Springfield Tire?

Can't tell from that serial number. The date of manufacture is the last 4-digit number at the end of the DOT code on the side wall. The first two digits is the week of the year, the last two is the year. that the tire was manufactured.

You should cut it in half and look at the rings and count them. Oh, wait, that is for trees.
