If the mechanics you are dealing with are telling you "that they seem to believe it's in the tires" then that is a good indication that they have not properly diagnosed your vehicle and are just throwing parts at it hoping that one of those parts fixes the problem.
You need to find a technician that has an EVA (electronic vibration analizer).
This is an electronic tool that senses vibrations and records their strength and frequency..with a few calculations the technician can determine what rotating componant or its related group is the cause of your vibration.
Vibrations occur from the following situations
Out of Balance
Out of Round
Damage
Excessive runout
Operational characteristics
componants contacting each other
improper working angles or phasing

The thing to remember is that there are componants that rotate the same speed as tires that may be the cause of your concern.
