So I'm driving my Vette from CA to Bowling Green and will meet up with the guys there. On my way across he country I notice a vibration. I have friends (yeah I really do) in St.Louis and can stay with them so I pull into a Chevy dealer to check it out. Seems my right rear Michelin tire (just put on before I left) is bad...not really round. Has anyone heard of 'road force'? The dealer said this tire recorded 33 lbs where the limit for this tire is 18lbs. This is NOT air pressure of the tire. Anyway. The Vette is up on a rack at the dealer waiting for a new tire to arrive. Now the warranty hassle with Michelin and the dealer. So my wife and I are at our friend's house wasting time. Hopefully we will make it to BG on Wednesday. I look at the the big picture and if problems are going to happen this is not too bad.
