As stated in the title, it's already in .m4r. Just execute the following you'll have them on your iDevice in no time

2) Extract the files in that folder.
3) Open iTunes and select Tones* just below LIBRARY.
* - If you don't see it, click iTunes (Mac) / Edit (Windows), select Preferences and tick Tones under Sources.
4) Drag and drop all / selected files in there.
5) Plug in your iDevice and click on your iDevice on the left in iTunes.
6) Navigate to Ringtones and ensure that it is ticked.
7) Navigate back to Summary and click Sync.
8) Once done, eject your iDevice, go to Settings / Sounds and select away!
