If you're having a problem with ssh, /dev/tty permissions have nothing to
do with it. It's something of a phantom device which always refers to
YOUR tty. YOUR tty will naturally be owned by you, and either 620 or 600
(depending on mesg(1)). Vis:

[18:10:13] mortis:~
(ttyp3):{672}% whoami
fullermd
[18:10:17] mortis:~
(ttyp3):{673}% ls -al /dev/tty
crw------- 1 fullermd tty 5, 3 Jun 8 18:10 /dev/tty
[18:10:23] mortis:~
(ttyp3):{674}% ssh -t -lmatt localhost "ls -al /dev/tty"
Password:
crw--w---- 1 matt tty 5, 23 Jun 8 18:10 /dev/tty
Connection to localhost closed.

So, something else would be causing your ssh permissions. We'd need more
details to try and track that down.
