just noticed that all four tyres on my VRS are wearing on inside edge - only done 3k miles.

Is this sawtoothing ? and can anything be done ?

Cheers

sounds like it, very early to happen mind! Noticed the noise on mine at about 8000 miles and one of them had started. Done 10500 and both rears are now wearing uneven. Great init! :(

More likely to be incorrect toe setting.

Really, all cars should have a full 3D geometry check and adjust at 2-3k miles from new. The cars will be set at the factory (probably not too accurately) but as the suspension bushes, springs and dampers settle-in there will inevitably be some deviation.

I had mine done at 2k miles and all the settings, apart from caster, were either out of spec or borderline.

Make sure you go somewhere that has proper optical alignment that can do the fill range of primary and secondary angles.
