Front tyre wear
Discussion

It's totally normal for them to wear in this way. You can have the camber reduced to lengthen the life of the tires, but you loose feeling and front end grip.

With almost any other car I would agree completely! But not with a Noble. Front wheels are set neutral with almost no negative camber (-0.5degree IIRC) and there is no way to change the camber short of going to Yellowshed or Plans and getting the uprights machined.
Both tyres have worn in the same way. It is unlikely that both ball joints are worn and the car has only done 14k road miles.
What is the solution ?
Is there no way of adjusting the geometry without remachining. ? What about ride height. Does that have any effect ?
The car does feel a little skittish at the front, but that could be due to now bald inside edges. Believe it or not, but these are still the originals.

What's the tread like on the remainder of the tyre? If it's pretty close to legal limit I wouldn't worry overly about the apparent uneven wear pattern. If you'd seen it after 1K miles then you've deffo got a problem, but after 14K on a single set of tyres, in a Noble?!? If want peace of mind then get the tracking checked by a reputable firm (but remember they will not be able to adjust camber)and then just get a fresh set of rubber. With some decent tread under the car I'm sure you'll have more confidence in the steering. Remember though, this cold, damp weather is going to make anything feel pretty skittish.
I find that cornering speed has substantially increased since I got the camber sorted out. I think I was using only cornering on 1/3 of the tyre before this was done. Now it's even wear on all 4 tyres. The solution was provided by Roush:- machined uprights and shims for adjustment. Some testing with Plans' help refined the setup further.
Cost:- £1000 plus VAT. Plans also offer this modification.
Really it's a no brainer if you track your car a lot; you get the money back from saving tyre wear and you're quicker.

The ball joints on mine wore out sooner than that. MOT failure at about 12k miles I think. I also still have the originaly tyres (see separate thread) but there was no uneven wear.
Sorry, I'm a bit brain dead today. Just getting over bad case of flu.
You are right, the camber is not adjustable on the standard setup.
You can get fully adjustable ones from http://gtstuning.com/ which will allow you to fully adjust your suspension.
