I had a quick look, cheapest 20 inch is contis at 200 a corner. Explains the difference.
Something's wrong if your only getting 10k out the fronts, I get more than that out the rear (think I've got PS4 or PS4S). I had my alignment checked and they said it was fine (at Kwik fit).I have a set of cs7 on a m3p. Alignment is spot on but they seem to wear on the inner edge more than other tyres I’ve had. I think the front will only get me 10k miles and that’s if I’m lucky. I don’t drive the car hard either.
