Icing sugar wheels

One of my fronts has decided that after 11,000 miles it is time to try a new shape which just happens to be oval.
Doesn't seem very much mileage to me, especially as it hasn't been damaged.
Is it a common thing or am I just unlucky ?
Interesting, do you regularly go over a steep bump or kerb and is it just the one wheel?
I've driven the car for the last 6000 of those miles and the wheels have never been kerbed or anything like that - I haven't run over any lumps of wood or anything like that either.
I do go over a slightly raised smooth lip at the entrance of the yard where it is kept on a daily basis but that is at about 1mph due to the usual clearance issues. It is about 1/3 the height of you average speed hump
It is only one wheel but it has clearly gained a slightly out of true shape. I first noticed a slight vibration about 10 days ago and thought a balance weight had come off, but when you jack it up and spin the wheel the problem is apparent to the naked eye.
I've since been told some bmw wheels have the same problem.

If you crash it into a pothole, or run a kerb on track, they have been known to go out of shape.
If you can't identify what you hit to bend it, and hence be able to make a claim against the council, then you can either get it checked out and balanced to make it "as good as it can be", or try one of the aftermarket wheels that are apparently stronger.

Same here. Compared to most other wheels they're made of cheese. Although it has to be said it's the same cheese as newer Audi ones.

That's the weird thing, I've driven lowered cars for years and developed a kind of 6th sense about potholes, ruts etc and I am absolutely certain I haven't done anything to it - it has just developed a bit of ovality with no sign of damage whatsoever.
I'll probably just swallow the price and replace x1 wheel, I'm not keen on trying to fix out of shape wheels.

I've not had any issues over the 3 years of ownership until I hit a kerb on a track day, so all I can summise for you is that it is related to hitting a bump.
Keep an eye on e-bay, M12 wheels turn up on there relativly regularly.

I do bow to your vast experience of Nobles, but not of my driving - I have not bumped, hit,nudged,bounced,clumped,scraped,scratched or even looked at the bl**dy wheel in an offensive way.
If it has been ovalled (?) by a bump which the driver could not feel then it shouldn't be on a car in the first place.
First wheel I have ever had to replace :-(
I have been looking on e-bay but as there isn't one on there at the moment I'm just going to have to contribute to Lee's hols fund as I'm not happy that it won't deteriorate further.
Thks for the advice

I've also heard of others managing to change the shape of the wheel on track day kerbs, and I think one driver did manage it on a pothole, but they do seem to take normal road holes pretty well. I've had to replace a Lotus Elise S1 and one of my Audi Ur-Quattro wheels from potholes on the road, so it's not exactly an isolated problem to Noble wheels unfortunatly.
Paul C has had some Dynamags made up that are much stronger, but they aren't as 'pretty' as the 3R spoke design.
One final thing, give each of the dealers and service centres a ring - sometimes they have single wheels that they are prepared to let go for well under list (I got a single 3R style rear that way).

Are you sure they are stronger? They are mag race wheels, so whilst lighter, they are even more likely to suffer on potholes, and of course mag wheels can suffer catestrophic failure whereas more road biases alloys tend to bend rather than crack.
Most race wheels are less strong than road going flavours. BBS certainly do not recommend the usage of their race wheels on the street.
