Tire Recommendation

[iameric]

I've had my car for almost two years now and I'm about to finish my second set of tires.

The first set from the factory were some kind of Bridgestone Turanzas and lasted me about 10 months. I'm currently running on Bridgestone Potenza RE050.
I figure I don't need any kind of Super Performance tire on my car anymore as I barely have enough power to move this enormous vehicle and it's nowhere near as nimble as a bmw.

So I'm looking for some halfway sporty tires that have decent grip, low noise/vibration, and decent tread life.
I don't need W Rated tires, and would prefer a tread life higher then 140AA.

Any recommendations?
Also Idk if it matters but I'm running 225/45/18 in the front and 255/45/18 in the back.

It would probably help (others, not me necessarily -- I'm not an expert) if you identified the "enormous," underpowered and non-nimble car you're asking for advice about. All I see are a Mazda, one or two Lexus ISes, a Honda and a Nissan 350. I thought you guys in Texas knew the definition of "enormous." :D
