Severe tire vibration, and not the impact of the low angle crash against a retaining wall, is being blamed in the death of Funny Car driver Eric Medlen, according to the Houston Chronicle. The report says that is what was told to NHRA POWERade Drag Racing Series drivers and crew chiefs in a meeting Friday morning. The report also claimed that the accident was blamed initially on a tire blowout, but investigative findings point to the extreme tire vibration caused by an unknown source or sources led to Medlen's head trauma and the tire blowout.
 
"It was some type of harmonics; the tire didn't fail," Funny Car driver Ron Capps told the Houston Chronicle. "It was a a big deal to hear from John (Force). It gave closure to a lot of us, knowing exactly what happened."
