I've never had wear like that with F1s on my T4(205/50-16) they have always worn pretty evenly apart from the very outer edge going down a bit quick, i have found they need to be 3-4psi harder than the recommended tyre pressures for it though. With rotating them I get about 15k out of a set and the do get driven hard. The car is always laser aligned every two years so I know the suspension is set right.
Some of us cant rotate due to tyre size differences.
. I only did it because it ment I got better life out of the fronts, when the outside edge started getting low I fitted them to the back.Got 15k out of mine.

I generally got 10-12k out them on my old Polo GTI and they also got the wear on the very outside edges but that was more due to hard cornering as it had full alignment checked a couple of times.
I have the F1 Asymmetrics on my current car and they have done 4.5k and are about half worn but they do grip very well and the new tread design seems to have stopped the wear on the very edges. Goodyear also claim the side wall is a lot stiffer, certainly feels sharper on turn in compared to the old Conti Sport Contact 2s they replaced.

Outer edge tyre wear is either caused by too much toe out or positive camber. Both of these will cause a front wheel drive car to understeer more. It can also, potentialy be caused by driving hard and forcing the car to understeer a lot. If that's the case you need lessons on how to drive your front wheeled hot hatch properly.
You should have slight toe out, probably around 15 minutes on each side for a total of half a degree maybe, and some negative camber of around half a degree on each side. This could give you a little wear on the inside edge but set right shouldn't prematurely wear out the tyre.
I have a little extra toe out on the front of my cupra to help it's naturally understeery characteristics, and accept the extra tyre wear.
While we're on the subject of geometry, whoever said that tracking and geometry are two different things needs a pasting. Tracking is just one part of the suspension geometry of a car and refers to the toe of the wheels on one axle. If you have bad tyre wear then you should have all of the geometry check and reset and not just the tracking/toe.
Also, incorrect tyre pressures wouldn't cause a tyre wear more on one side than the other. An underflated tyre would wear on both edges more than in the middle and an overinflated tyre would do the exact opposite.

My tyres are never under inflated, and the alignment is fine also, i will admit i did do a few miles with the alignment absolutely miles out due to a garage having no details for the car on record and having to guess what it should be set to, but it was re-done by some place else & then re-checked a few weeks later and all was spot on.
I've never had problems with them on my 172 or the 1.6 I had before. Always worn evenly and i've always got what I thought was acceptable miliage out of them for how soft the compound is (8-10k). The only problem i've had is the 172 is eating through the fronts rather more quickly than the 1.6 did, although thats probably me

.Never ever ever have I pushed my car to understeer. It will only understeer right on the limit of grip and then I simply lift off into a bit of oversteer. Yet the outside of both front tyres is bald wheras the inner edge and middle bit is fine. The car is standard and doesn't have positive camber, it could probably do with a bit of negative but sadly it isn't adjustable.
