Hi. 37th & 45th week of 1992, 1982, or even 1972 maybe.

I believe four digit dates (last two of last two of year) started in 2000.

They’re at least nearly thirty years old.

Cheers.

They are Goodyear Wide Tread GT. Did Goodyear continue making them after they went to Polyglas ? Repo ?

No tread wear indicator and no safety warning.

Those tires were made in or after 1971 which is when the United States Department of Transportation mandated all tire manufactures use a standardized 10 digit DOT Tire Identification Number.

Goodyear Wide Tread GT RWL tires which came on 1968 and 1969 Z/28s will not have that DOT + 10 digit number sequence
