The current focus rs is supplied with continental contact sport 3 tyres,supplied only direct to ford and bmw..... these tyres are not available anywhere else,
i can get these tyres from my local tyre suppliers, i fitted a set on my car about two years ago and the fronts are still going strong over 15k later the only reson i had had to replace the rears is because the archs damaged them, so i cant see it being the tyres fault
