Should I replace this tire?

That would make it a DEFINITE no-brainer. A 3-digit code was made before 2000, so that tire is already 20 years old.

More specifically, it was made in the 43rd week of a year ending in 9. Could have been late October of 1999 or even late October 1989. Either way, it's too old to use and not old enough to be in a museum.

That is the best ---
