Tape TTL

Have been looking for any recommendations about how long I could use a tape
before it´s necessary to change them to new ones. I know that it´s up to how
much a tape have been used, mounted, read, written and whatever. Or is it ok to
use a tape until it failures?
Below is details about 2 of my tapes, where 000051 is more typical of the most
of my tapes, and 000007 is very rare in my library. How come that the most of
my tapes are only mounted between 5 and 20 times since 1,5 years back? I do
backup between 450 and 600 Gb a night.
Thanks for any recommendations or thoughts around this matter.
