Even semi-bad tanks can do this, whereas if they have to take the adds, they usually fail and cause wipes. So be happy that you have one of the "harder" roles that you can control.
But to talk a little specific about jaraxxus (normal mode) since you mentioned it. If the other tank is a warrior, put him on the adds. Even if he is usefull on jaraxxus since he can interrupt (other classes can do this to, *kuch* rogue *kuch*), he is far more usefull on the infernals since he has a zillion stuns to handle their aoe.
