Are you sure you want to this? Reasonable values are 620 and 600,
depending on whether you want to allow users to write(1) messages to
each other's terminal's. What's the point of giving read access to the
tty group?

Mounting of /dev/pts and various other API filesystems is hardcoded in
systemd, look into src/core/mount-setup.c if you're curious.

In the file that provides the API for mounting filesystems, i.e.
/etc/fstab - see systemd-remount-fs.service(8). There is no entry for
/dev/pts by default, so you create your own, like this:
devpts /dev/pts devpts defaults,gid=5,mode=660 0 0
