And I bet you haven't used it much 
Seriously, it would be good to compare to the 912, although the 452 I've driven on an Omega were shite, but the shagged suspension might have made it worse... ...or better 
(Tunnie, your old heap was on 452s for a while?)
452's on rear 912's on front, still there, 35k later 
On 2.2, brilliant tyres. 912 had longer life, but they were on front not back. If/when the 2.2 is pressed into service again, I'd fit them again 

they do seem manageable at lower speeds, and less... Enthusiastic driving in corners may help them wear with a flater profile.
Absolute worst combination would be Elite suspension, press on driving style, 912....which last longer, there by allowing body roll and hence camber deflection on the front to wear the tyre more on the edges. The longer the tyre is on there the more rounded the tyre profile becomes and the more it wants to roll off high points and undulations in the road. It's like it deflects around bumps, rather than riding over them.
I'd be interested to see what construction techniques tyre manufacturers use to achieve thier various tyre characteristics.
Needless to say, high speed runs, on my private test track, are extremely hairy with these tyres fitted. A condition that appeared instantly once fitted, and no doubt will vanish again once sc3 or any other tyre, goes back on.
On the other hand Mr Daisy probably won't notice the instability, and appreciate the quitness and comfort alot more.

( as said I do miss certain aspects of Falkens personally, just dont tell anyone I said so
