It might be worthwhile having the steering geometry checked by a specialist, perhaps when you get the tyres changed. Will you be looking for Michelin ES which others have found to be good in both performance and longevity?
Quite probably. They seem to be around £100 per tyre but then the Dunlops are around £90. Cheapest is £65 but I never buy the cheapest. Tyres are the only thing holding the car to the road so it's worth taking them seriously.
From looking at the tyres there's no scrubbing, the wear is symmetrical and there's no steering drift. I'm also getting pretty good economy. I can't currently see it being a tracking problem. Reading around it doesn't seem all that unusual. The rear wear is higher than I'd expect as well so I think it's just soft compound and somehow the tyres can't take the way I drive.
Much as I'm no speed freak I do take corners faster than a lot of drivers and when I move off I like to do so at a decent rate of acceleration (straight to 3,000 rpm to get out of the Atkinson cycle). Then again they don't experience much braking force as I consider using the brake pedal for anything except stopping to be the sign of a poor driver.
I'd concede that while my tyres don't have a violent life they perhaps don't have an easy life either. But normally I'd expect 15k miles out of a front set based on my previous Jazz. Either the Mk3 suspension is making wear worse or these tyres are soft. My driving is the same.
