Had a problem with one of my BFG Commercial TA's

So you change tires on all your cars, your truck and your RV when they're 5 years old even if you've only worn 2/32" off them?

Shelf life means tires should not be sold if they're 6 years old, most websites I'm finding recommend changing them if they're 10 years old.

Near as I can tell they were made 04/11, the same time as the other 2 sizes
that are being recalled.
