TouchCopy can copy two types of ringtones from your iPhone to your computer:
If you have not done so already, you can download TouchCopy from here:
This option is best for ringtones you bought from the iTunes Store. Your copied ringtones will be saved as .m4r files on your computer. If you don't see any ringtones here, try Option 2 (custom ringtones).
The files ending in .m4r are your custom ringtones.
If your tones have random file names, that's normal — you can still copy them and rename them on your computer. Once they're saved to your computer, you can rename them using your computer's file manager if you wish.
