If you're going thru tires that fast, at least don't buy the pricey ones. I know several people who have the Hankook Ventus Evo K112's or whatever they are, and they like the performance. (MS3's and MINI Coopers) But I don't know anyone who has worn out a set of the Hankooks yet, so I can't report on actual miles driven.
I've been thru 2 sets of Yokohama S-Drives on my old MINIs, getting 25k each from them, compared to under 20k (and as little as 12k) from other tires. And I have about 20k on my current S-Drives on the MS3, with probably another good 8-12k left. MS3's alignment is much easier on tires than the MINI's was.
Daily driving, I'm slightly aggressive, but not drag racing from light to light or trying to find the apex of the Circle-K driveway every morning. I do have a trip to Deal's Gap (to enjoy the twisties) on this set of tires as well.
The Hankooks or S-Drives should run you in the $90-120 range for most common sizes, so even if you tear thru them, at least you get off cheap.
