			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 |
