How much is it coned? Smaller diameter in the inner side compared to the outer or vice versa? If smaller diameter in the inner side, then it's good. Not too much though.
Anyway, set the rear camber so that it's just slightly coned (smaller inner diameter compared to outer). For the front tires, make sure the camber is enough to make them wear flat.
Thanks D,
Right rear coned more than left rear coz running clockwise so I think the left wears more on the outside. Right rear coned as much as 1.5mm.(diff between outside and inside dia.)
And I'm running only 2deg camber.
So what's reasonable amount of coning for the rear tyres? 1mm diff?
Cheers...
