new mondeo

have 10 month old mondeo titanium x back tyres worn down to the metal for about 1and 1/2 inches on the inside,car has done 8500 miles and is driven conservatively as can be proved by the condition of the front tyres,ford says wheel alignment is the problem,my warranty book says that I am covered for 12 months or 12000 miles I am under both but they now say that they have changed the warranty to one month only for wheel alignment,talk about moving the goalposts,obviousely there is a reason for this,ford must be having big problems with this,so the question has to be asked are they fit for british roads?,annoyed they wont honour the warranty that I hold in my hands,nor will they offer any "good will " as they call it,my car was a potential death trap and yes maybe I should have checked my tyres sooner,but you do expect the car to be better than this,are there any people out there having the same sort of problems,is it a fault with ford or m I just unlucky to have this car,got to admit I did expect better from ford,just goes to show once your money is handed over nobody cares
