Hi,
As far as the tires are concerned, do they have an aggressive tread? They usually always cause a vibration after some miles of use.
Under the seat, there really isn't anything that would cause a vibration unless someone has changed the exhaust system and it is against the frame or bumping the frame.
I have a question. Is the noise loud enough for you to record and upload for me to hear? Let me know that. Also, let me know if there are any drivability issues with the vehicle and what modifications have been done.
Take care,
joe
