It's to do with the construction, as Tunnie says they are exceptionally quiet, which means a soft sidewall, and the way they wear, and the number of corrections needed to keep the car straight as they wear. And yes it does depend how you drive, due to the way McPherson strut suspension adjusts the camber to body roll.
They tram line from new, as a set of 4, if you only have them on one axle you'll half the effect.
They have a soft construction.
Add in soft Elite suspension. And hence camber deflection.
A progressive driving style in the corners. That makes the camber deflect.
...and after about 1/4 of the tread has gone you'll start to notice the car wandering around. Difficult to keep straight and a disconnected feel at the steering wheel.
By about half worn the car becomes impossible to keep in lane on uneven B roads above 40mph.
Proof..? Fit wheels with totally worn out Dunlops car drives straight as a die. Refit Falken shod wheels car becomes dangerous again.
Now Miss Daisy earlier in the thread drives so slow his Elite suspension doesn't need more than an inch of travel, as he never induces any body roll, therefor the suspension doesn't move and the camber doesn't deflect, so the tyres don't wear the edges as much.
I've driven other members cars with Falkens fitted and the owner is quite happy with them, yet I can feel feedback thought the steering wheel that's tell tale of Falkens, that simply isn't present on other tyres.
As to why Wim/Blackboots recomend them? Any tyre shop will sell you any tyre that will fit. They don't care what you buy, that's your choice, and once they go on the rim, they are yours, your stuck with them, tuff luck.
To be fair Falkens do sell. Good midrange tyre etc. ...on Omega they are cheap basically. No grip, no stability, poor wear, no stability, tram lining, no directional control, and in case I didn't make the point clearly enough, no directional stability. At all!
Although they are exceptionally quiet. Vey very quiet indeed.
Bit don't worry, I recomended them on here too once. As I fell into the trap of forming an opinion of a tyre as new. Rather than over the entire tyres life.

If fitted on the rear with a steady driver, you might not notice. But I see you have an Elite, so I guess it won't be long.
