Rumble or Vibration

[rrs26ja]

Yesterday I started to feel a vibration or rumble. It is noticeable at all speeds but I can really notice it around 60 mph.

I am hoping it not this transmission vibration I am reading about. It sounds or feels like a bad tire, maybe a broken belt. What's weird is that I did use the emergency brake a couple of times a day or so before.

Any ideas?

I have the same rumble sound around 58 to 63 mph. The sound is very faint but it's there. The shop couldn't find anything wrong, but I'm going to ask them to look again. If you find out anything, please share, thanks.
