Re: DOT date stamp on my Tires
Reply #10 –
DOT code "375" indicates week 37 of 1985.
DOT code "375*" indicates week 37 of 1995.
Some manufacturers used a small triangle, or a delta sign instead of a "*" during the 1990's.
This subtle difference can be difficult to detect because the 90's indicator is not always within the smooth flat circular surface where the date numbers are embossed.
