mine was doing that for a while it would start at 63-65 and go away at about 75. I thought it was the tires and ran it for like two months then I jacked up the front where it was coming from and could tell right away what it was since I could move the tire probably a good inch top to bottom lol. Fixed the bearing and the tires are quiet as could be and no vibrations im glad I found out when I did cuz I was gona order new tires the next day cuz it was driving me nutts.
