Depends on where you live, etc. so far the best tire I have had, in terms of cupping, or lack thereof, are the Kumho ECSTA Platinum LX

I couldn't stand the Contisport 5P runflat tyres and got rid of them with 4mm of tread on them. I got Michelin Pilot Sport Cup 2s and I can really recommend them. Before I fitted them I tried a simple brake tests from 70mph and then again(same weather conditions) after I fitted the tyres and they had covered a few hundred miles and the car stopped between 30 and 40ft quicker each time. The ABS hardly if at all kick in. As for cornering, well you can guess I'm impressed with them. Okay they only come with 5mm of tread but they are worth it. To give you an idea how good they are, they have more grip in the wet (very wet) than the Conti tyres had in the dry.
I am currently running Continental ContiSportContact 5P. They are even stickier that the ExtremeContact DWs I had on my W8. I have two summers on them and do not have any cupping, I have only have been rotating front-back.
Pirelli Nero series, or if you want that round look with quite a lot of performance then Pilot Super Sport...
I just saw a sedan with this package and it looked like quite an upgrade compared to a regular Focus. Playing around with the configurator it doesn't seem like it is available on the hatch for some reason, but it really changed the character of the sedan. The tires are wide and it looks hunkered down with a restrained body kit.
These are rare, look great and are durable. The tires only have about 5k miles on them and show minimal tire wear.
I've always had luck with Neogen's and they tend to stretch really well.
I'm running 215/40-18 Nitto Neogen's on my 9.5" without a problem.
215 on a 9.5.. i must however say that falken 512s stretch much better than these(although i was happy with how my nankangs looked on the c5's)
the stock P-Zero Neros are garbage. I've replaced all 4 of mine. I have two of them with a decent amount of tread sitting outside because I couldn't bring myself to toss them, but they really suck.
