As far as I can tell, the default for /dev/tty* is mode 0620, and the group owner being tty. No users should be part of that group.
There's at least nwall, which is setgid tty: $ ls -l /usr/bin/nwall -r-xr-sr-x 1 root tty 17988 Nov 14 21:30 /usr/bin/nwall
So no, you don't need to remove the +w part from the tty group.
Yes, you do. -- Jakub Wilk
