I guessed high on that tire. It is 23.65".
So in 3rd @ 55mph you are at 4,150rpm
4th @ 55mph you are at 3,025rpm
I highly doubt you will see any ill effects from compression braking at 4,100rpm. But depending on how your ECU is set up you may be using more fuel at 4,100 than 3,000 so running it in 4th and using the brakes a little could be a better method. That all depends on your "tune" though and I wouldn't know where to find that info at.
