Goodyear tire manufacturing date
Posted by Greg on November 29, 2006
I purchased a 1970 Corvette with Goodyear Wingfoot 255 r60 15 tires on it. I can not find a date code on them and I am trying to determin how old the tires are. They are in great shape but I am concerned that they are too old it be trusted.
When did they stop making Wingfoot tires?
The following quote is from the National Highway Transportation Safety Association and it details the U.S. DOT Tire Identification Number and what the letters and numbers mean.
"This begins with the letters 'DOT' and indicates that the tire meets all federal standards. The next two numbers or letters are the plant code where it was manufactured, and the last four numbers represent the week and year the tire was built. For example, the numbers 3197 means the 31st week of 1997. The other numbers are marketing codes used at the manufacturer's discretion. This information is used to contact consumers if a tire defect requires a recall."
