Well had this happen on the way home today, heard what sounded like metal rubbing metal, there wasn’t any sort of vibration, but it was progressively getting worse. Planned on taking a look once I got home, but this wheel adapter had other plans. Came flying off while going 55mph down the highway. Luckily as I heard it get worse and felt the pop, I had already begun slowing down, once it let go all the way, I managed to pull off the road and come to a sliding stop in the grass. Even luckier though, the tire didn’t collide with any oncoming traffic as it went speeding past me. All I could do was sit and watch as it raced away for about 100 yards before bouncing off a tree and landing in a ditch.
