Renault Megane CC 07 - Odd Uneven Tyre Wear - Growing Place

All tyres on the car have a tread of 5mm 0verall with the exception of the OS Rear Inner which is 1.8mm -- anybody any ideas as to why as as a layperson if the camber is wrong then both rear tyres would be worn to the same amount.

Enjoy the sun!!!

Renault Megane CC 07 - Odd Uneven Tyre Wear - RT

On cars with independent rear suspension, one wheel may have the wrong camber but not the other - but if the camber's wrong it normally wears as a gradient across the whole tyre, not just on the edge.

Sounds more likely that the rear toe-in is wrong for one wheel.

A full alignment (not just tracking front & rear) will show any things out of setting - but not always correctable!
