Tire date codes
 
I googled this, but couldn't find anything that made sense.

I have a set of BFG tires with date code:

DOT BFOR821333

Anyone have a method to decode this and figure out how old they are? From my search, it seemed like 1993. Yikes!

The 4-digit (e.g. XXYY, week/year) date coding didn't start until 2000. Before that it was two digits for week and a year digit, so 33rd week of probably 1993.

Is there a noticeable gap in the last part of that code? Like BFOR821 333?

If you suspect old tires, they're probably old tires ;)

I've heard that tire manufacturers are now being required to go away from the date code system to another system that's more clear to the general public.

Is that the long code or the shortened one?

there are no spaces between the numbers. And I don't know what long vs short codes are.

Seems like based on the numbers it must be 1993, which means these are some potentially sketchy tires that I don't have $ to replace right now. Wish me luck ya'll. :o

So then, if these don't have the 4-digit code, then they're older than 2000? which means probably too old to run. :(

The tire should have different length codes on opposite sides of the tire. The long code is the one with the dates. So check both sides of the tire. but maybe that was 2000 and after life dave stated. dunno.
