I need some help picking new tires for my 06 g35 sedan with the stock 17" rims.

I have narrowed the choice down to the following:

Kumho ecsta asx $83
Yoko AVID v4s $123
Continental Contiprocontact $127

ALL tires are 215/55/17 and current prices are from tirerack.com

I live in Central FL, but I still want all season tire because I go up north sometimes during the winter and don't want to swap tires. I value longer tread life over extreme performance as well.

Thanks for the input.
