Final post and some good news. After the alignment correction the car does not pull to the left any more than would be expected due to the camber of the road.
Better still, I just received news that through the ford dealer that sold me the car, Ford have offered to pay half the cost of the tyre replacement ($180). I'm happy and a bit supprised by this but I didn't expect them to even give me the time of day considering that the even tyre wear across the tread and lack of pulling to the side are not explained.
Thankyou everyone for your comments.

PS: Its only 800Km on the new tyres but I've noticed that average fuel consumption according to the computer has improved from 8.2 to 7.3 L/100Km. Nice when the rear wheels don't fight the front ones!
