I screwed up the photo of the date code. I’m missing the last part.
I did not see any weather checking.
If they are over 6, I'll just replace. Depending on the spare, the best one might get kept for the spare. Hell, I might keep them all, and just let them go with the F250 as spares if they aren't too much over 6. And truth be told, I'd rather have highway tires on it for better fuel economy. My F250 instantly lost 1mpg city and highway when it got all terrain tires, vs the worn out all seasons.
