Very interesting - thanks.
I've known for many years the last little bit of tyre wear seems to occur in rather less distance that one would estimate, but to go from needing replaced soon to utterly worn out in 260km is worrying really.
Wear pattern suggests the toe out is perhaps excessive but were this true, I'd have though the car's handling would have given a clue long before the tyre wear became an issue.
As it's a dealers car, you perhaps won't learn what the cause was, but if you do, please post as I'm sure others are interested! It is to be expected a dealer car will lead a hard life, but conversely, ought to be very well maintained, ho hum.
