Who knew decoding the tires would so complicated?

I do some work in a Goodyear plant and the white numbers on the tread are their part numbers used when assembling the tires. You may be suprised by how many "parts" are used to make a tire. Back in the day all tires were hand assembled. After they were assembled they were cooked in the mold to valcanize the rubber together. Heat will take a tire back apart, that why you see treads of truck tires on the highway.

The date codes were screwed into the mold every day just like the casting numbers on engines.
