you need to take it back to seat and complain that the tyre wear is uneven and they will carry out 4 wheel alignment should correct this if tyre pressures are ok i had this on mine when i bought it but fine after the alignment
just clocked 14,000 miles since march.
may put front tyres on the back now.

For superior braking in the wet perhaps?
When braking in the wet from 70mph 3mm of tread on your front tyres will see your stopping distance increase by up to 20 metres further over the distance if you had 6mm of tread.
What is the more likely scenario - losing the rear driving like a t*t round a bend in the wet or rear-ending someone who's stopped a bit sharpish on the motorway?
What happens more often every day?
They all do it, if you contact Seat thats how they are set up lol.
Replace the bushes which will slow it down, but you wont ever get rid of it.
All I can say is if you nearly got 10k out of front tyres, well done.
The point about needing the deeper tread on the fronts was made during the last series of Fifth Gear IIRC - local Ford dealerships are also currently running a promotion/advertising campaign based on this showing wet-weather braking distances are increased by anything between 7-40% depending how far off maximum depth your front tread is on.
To be honest I'd rather trust the manufacturers, not some television program, who say that it is MUCH safer to put the best tyres on the rear, try taking your car to Costco (who only supply Michelin's) they will refuse to swap them as Michelin have told them not to do it.
Ford are totally correct, but that is not an endorsement to put the best tyres on the front, but warning people to get their worn tyres changed.
Have a look at this video of someone as you said driving like a t**t

Each to their own, but I know I'd rather drive sensibly in the wet, don't tail gate people and know that my rear is not going go on me without some prior warning!
