When to use a tritone in a blues progression?

Another common usage is in a 12-bar blues progression. A typical 12-bar blues progression looks like this: I7 ⇨ I7 ⇨ I7 ⇨ I7 ⇨ IV7 ⇨ IV7 ⇨ I7 ⇨ I7 ⇨ V7 ⇨ IV7 ⇨ I7 ⇨ I7. A tritone substitution would occur in bar 4, when the I7 chord is about to transition to the IV7 chord, changing that I7 chord to a bV7 chord.
