I currently have Bridgestone Potenza tires, which came with the car when I bought it...but they need to be replaced and I'd like to get something less expensive & I've had bad luck w/ Tire Kingdom :(

What's my best choice? They are size 235/45/17 and W speed series. I've been considering the Falken FK-452 tires or the Yoko AS430, but the store recommended Sumi HTR Z II...I don't know anything about this. I would like all season tires, but I never drive in the snow-I'm in the south-it's either hot, cool, or raining here. Any experts have some advice for me? Thanks!
