That seems terrible tyre mileage for such a small car.
> I wonder if there's a sweet spot - premium= more grip and poor wear, midrange, harder rubber, less grip but less wear? My only experiences of cheaper tyres has been from buying secondhand cars already on Barums or whatever, which offer no grip and no tread life. I like grippy tyres but, to paraphrase other posts, I keep an eye on the tyre wear myself. >
Michelins used to have a reputation for lasting ages, my first car had them on and the rubber was almost perishing before thye tread wore out. A few years ago we stuck Michelins in my wife's car (Peugeot 406 diesel, so again, quite a heavy car) and they didn't last any longer than the mid price tyres we normally used so I've never bothered with them since.
I've never noticed any real difference in grip regardless of what tyres are on my car, perhaps that's a reflection of how I drive?
I wonder if I get decent mileage out of tyres because most of my miles are on motorways and A roads i.e. straight lines, very little turning and manoeuvring? Before I bought my car (VW Sharan a.k.a. Ford Galaxy) I'd heard of its reputation for eating tyres (c.15K miles) so was pleasantly surprised to get 30K out of them and even that was only because the tracking was out (now fixed) so they wore unevenly, otherwise I'd have got more.
