My Pirelli 275/35R20 rear tyres have worn more on the outside edges which is surprising given that others are experiencing wear on the inner edges? I have completed 26,000 miles so cannot complain both tyres are down to 2mm on the outside ; 3mm in the centre and approx 4mm on the inner edge. I will have the camber and toe angles checked when I replace them. I'm nervous about changing the camber given the experience of others but in theory the readings should show a positive camber on mine where as usual BMW set up is for a slight negative camber.
