MHZ4C said:It's similar for my E86. When I hit 2-3 mm across the rear tyres the inner edges were well worn, but no cord showing.
I believe it's normal with standard negative camber settings. I'm not sure if the rear of the E89 is set up the same as the E86 but it would seem logical to have similar camber.
I still had full wear from the tyres, and an MOT place wouldn't fail the tyre on excessive wear due to the 2/3 of the tyre wear rule, as long as the worn edges are not showing cord or excessive damage.
