tire help

Okay, after 52k miles, the tires on my Mustang are shot.

I don't know dick about tires, and if any of you are car enthusiasts, or know car enthusiasts, and can answer this question for me, please do.

I'm shopping for tires right now that are rated for my car. They range from $130 each for a Dunlop FM901, to $293 each for a Goodyear Eagle F1 GS EMT.

Every description I read for these tires talks about the great handling they provide, none of them give an estimated mileage, they all just say "great handling and traction", blah blah blah.

They all seem to have 1-10 ratings for "dry traction", "wet traction", "snow traction", etc. However, the more expensive ones don't necessarily have better ratings on these numbers. Some of the cheaper ones have better ratings. But these are all "performance" tires, they all have pretty high numbers.

So my question is this. What's going to happen if I pick the Dunlop tires? Are they going to wear out faster? They have good ratings for traction and everything, but I don't want to make a stupid choice that will cost me later on. I just can't imagine paying $1200 for a new set of tires, when I could get them for $520. But I'm very happy that my current Goodyear Eagle tires have lasted 52k miles, too.

How the hell do I pick a tire? Help.
