tar(1) will preserve user & group info if possible. From the manpage:
-x
--extract
--get Extract files from an archive. The owner, modification
time, and file permissions are restored, if possible....
However, I think you are correct. The files become root:wheel because
the original owner/group don't exist on the target machine (user yoshi
and group users don't exist on my machine):
