How to Sync Ringtones/Tones to iPhone?

1. Connect your phone to iTunes
2. Drag and drop your ringtones to On My Device – Tones
3. Click Sync button.

Apple removes the Tones tab in latest iTunes 12.7 update. In other words, tones tab missing from iTunes is one of the changes Apple made, and it is not an iTunes problem or bug. So there is no way to fix this iTunes Ringtones/Tones tab not appearing problem.
