If the tracking is optimised, the tyres should wear evenly right across the width. Mine wear flat and they are 225/60/17. Low profile tyres are more fussy and scrub out easier then higher profile tyres.
The trick is to set the tracking spot on
i had mine done with a four wheel laser alignment and must say theyve worn evenly as well , mine are 215/65/16
often see the extra low profile tyres on bmws etc and the alloys are destroyed where they've smacked them up kerbs etc
