She doesn't drive hard at all! Certainly nothing to warrant this kind of wear.

The current tyres are Dunlop SP Sport 01 DSST 205/40R18. I found this - http://www.tirerack.com/survey/SurveyCom...P+Sport+01+DSST (Sorry the URL link doesn't seem to work in my browser today) - which isn't very complimentary!!

Treadwear rating is 280, which isn't particularly low.

Hopefully, Mini customer care will acknowledge some endemic issue and replace them free of charge with some non-problematic ones, but I suspect that may not be the first offer!

I wonder if the run-flat nature (that is the DSST I believe) has some longevity side-effects on this one....
