Both my front tyres are going to need replacing because they've worn almost all the tread from the inside. The rest of the tyre is fine but the inside is completely worn? It looks like the kind of wear you'd get if you were running lots of negative camber, but I'm not as far as I know. My friend said it could be the tracking but I'm not getting any vibration through the steering wheel and the car feels fine? The tyres have been on about 10K miles.
