Usually a vibration is due to one or more parts that have become worn or damaged. I'm not sure why you mentioned the tires but don't disregard them unless you know that they are fine. Check for correct inflation (on the door jam), for uneven tread wear, or bubbles and damage.
Other things that can cause a vibration is the front-end needing an alignment, a tire that is unbalanced, worn out steering components (like a wheel-bearing), defective u-joints and/or an unbalanced drive-shaft, or low gear-oil level in the drive-axle can cause damage to the ring & pinion gear. The damage would primarily be on one side. So when you let off the gas pedal the sound goes away. Check as much as you can and let me know how it is going.

I had the same problem. Vibrations start around 40mph, up through 60 . seems to be ok when I am off the accelerator. The problem was not dirty ETM rather a busted passenger side cv boot and axle. Fixed it and the problem is gone. The part from Volvo its expensive. Over $500. But OEM part can be had for less than $200. I have a 2003 s60 T5.
