Greetings,

I recently noticed in my Accord 2001 vibrations that occur (or
noticeable?) only when I go above certain speed (obviously in the
highway). It would be safe to say that it occurs above 60 mph.

I don't remember having this kind of noise before. I bought the car new
in summer 2001 and I have been servicing it according recommendation by
the car dealership I bought it from. I also change tires twice a year
(all season to snow and back).

Since I would like to be better informed when approaching my car
serviceman, I would appreciate it if you could tell me what could be
probable causes of such vibrations. Visually inspecting the tires, I
don't notice anything special. However, I don't know whether to rule
out sloppy tightening of lug nuts, etc. Is this kind of vibration a
know problem in Honda Accords?

Thanks!
Sam
