Tyre wear

[Splant]

Is it normal for the outer edge wear more than the inner? When you're driving like a loon around bends etc, I've also noticed them squealing on supermarket car parks when driving slowly, but heard other cars do this to!
To give more toe out I guess the track rod end has to do a full 360 turn ,no slight adjustment then?

Yes, rotate the TRE a full loop which if I recall is about 1.25mm adjustment
If you've got sharp tread blocks when you run your hand across the tread side to side, like inside to outside then it's a tracking issue, as the tyre is being forced sideways as you drive.
Camber issues which can produce the uneven wear when comparing inner to outer wear doesn't produce the sharp edges to the tread blocks.
You may need to do a couple of turns if it's visibly wearing the tyres, ideally one turn each side. Maybe more.
But guessing is fools play, get it on some tracking gauges but free stuff off and make sure the ends come out of the steering arms before taking it in or you'll be met with frowns and harsh words
