You replace whatever wears out when it wears out.

It's hard to tell if you're serious or if you're just trolling because I
already said multiple times in this thread that a palpable feathering
occurs at around 4K miles, which is normal for some vehicles driven under
certain conditions, even when tires are properly inflated and suspensions
are properly aligned.

What on earth is the point in moving them around so you have
to replace all four at once?!

While readjusting the assembly static balance and tire pressure (if
necessary) is more of a comfort than safety issue, there's added safety in
inspecting the tires closely periodically to look for damage and to pluck
out objects, where invariably between 50 and 100 pebbles and shards are
removed from each tire in each rotation cycle.

So that's roughly about 50x4x4 objects removed every year from your tires.

How many of those 800 objects would eventually cause a blowout?

Maybe fewer than 1/10th of a percent, but this tiny shard I removed
yesterday certainly had a slow-leak potential:
