Rotate the tires. If the vibration is better or worse, then suspect a tire problem.

 

^x2. You could also have the wheels balanced at a tire shop. I had a similar problem years ago and a simple balance made it go away..

 

You might want to find a place with a Hunter GSP9700 balancing machine. That pushes the tire against a drum while it's balancing it, so it can find problems within the belts of the tire.
