Use `x-show-tip'.  Specify whatever you like.

E.g.:
(x-show-tip (propertize STRING 'face FACE-YOU-WANT)
            nil
            nil
            TIMEOUT-YOU-WANT)

Or bind the relevant variable(s) around a call to
`tooltip-show', if you like to jump through hoops
and you really don't want to call `x-show-tip'.
