for non-sequitur of the year

I was going to make a comment as well, but it's Christmas and I was feeling charitable

Sorry Aggy, I see you're a relative newcomer to the forum, well, returned after a while - aleem, whose post I didn't see at the time, has provided you with more constructive leads!

Incidentally your 21-post count doesn't tally with the actual 7 showing??

Ok, ok, they are to warn you if the wheel it turning or stationery.

Common myth. They're purely decorative. The equivalent of us lot adding spoilers and alloys to our cars.

Are they not in fact indicating on dials what the tyre pressure readings are?

Price tags for the bolts?

It's important to know if your wheel is made of paper.

Very important. You don't want to hit a puddle and have them disintegrate.

A wheel "on the turn"

Does that mean its "at the point of change or "is about to go rancid"?

Either way, it would be good to know I suppose..

If it's still edible or not.

Paper wheels seem to hold up okay on the Audi A4...
