Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Last winter I posted that I had a really bad vibration when the car was first driven each day. It disappears after a few miles and the car is then fine for the rest of the day. Well it's back! :frustrated:
It feels exactly like a wheel balance problem, and I have a vague recollection of a theory that ice sometimes from pools of condensation within the tyre?
Has anyone else heard of, or experienced, this?
I really can't think of a better explanation, but would be surprised if there would be enough water in there to cause a balance problem...
Thats a tough one but what about this this theory.
It sounds like its a winter/cold weather induced problem.
Car tyre is soft all day due to use and slightly higher daytime temperature.When you then park car up at night, colder temperatures could harden tyre compound.
Next day, tyre is cold,compound is hard and it has a "D" shape until driving the car puts some heat in the tyre and the compound softens and tyre is an "O" again and vibration gone.
It sounds as plausable as condensation in tyre freezin'
Wattie you could test this theory by over inflating them (for a short period only) it would reduce the D. Sounds a bit of a long shot to me as all tyres must do this.

I've never heard that theory before to be honest but I suppose its possible. Presumably this can happen on any car and if so I wonder why I have never heard of this before. Of course I'm no oracle but presumably you have ruled out other issues.
What about the rubber steering arm bushes. Perhaps when it's particularly cold the rubber loses its fexibility therefore more prone to cause vibration and then when the car has done afew miles the rubber softens....
Wattie, I'd be quite concerned if you had that much moisture in the tyres to cause what you hypothesise. Assuming is goes away after around 15 minutes I'd put it down to flat spot tyres from standing. I've always had this problem with R-Comp rubber. In fact, you would know what it can do - my car's ECU failed from it at Silverstone when you were there. I'd come in too soon and hadn't cooled the tyres enough. They flat spotted / flattened so badly that the vibrations caused an ECU issue.
Prove the theory by putting the car on stands one day
