Theoretically, all season tires can perform as well as summer tires. In practice some all seasons (like Michelin Pilot Sport A/S Plus) do outperform many "summer" tires. The key is to consider what the car is intended to do. How many 370Z's actually need the level of performance the Bridgestone summer tires claim? If Nissan followed their own logic, only the NISMO would come with maximum performance summer tires. It's the Z Nissan says it intended for racing.
Most of the rest of us will find no performance issues with really good A/S tires. I swapped the Bridgestone Potenzas for the Michelins in October. Even on warm roads, the Pilot Sport A/S tires do better than the Potenzas on wet roads. I admit that I am not racing, but I do drive in a "sporty" manner much of the time. I live in an area that is frequently wet and has roads I can enjoy the speed and handling of my Z when I drive.
In my use, the Michelins stick better than the Potenzas. That's not to say on a track the Bridgestone's wont prove better. My point is that the Z has a special place in the sports car market. It is affordable by people who can't afford multiple sets of tires. Also, other sports cars come with A/S tires.
I wish Nissan would do the same for all but the Nismo.

Listen, if i lived in seattle i'd probably have gone with all season tires too, and for your circumstances all seasons seem to be the way to go. However, someone living in the north east, if you plan to drive your RWD sports car in the winter, you need a set of winter tires. All seasons wont cut it. So there would be no point on having the Z come with All seasons. the only real advantage all season's have over summer tires is wet performance, and you can drive in colder weather, snow still is a no go.
and bottom line is, the Z is a sports car. Regardless of its price point, its still a sports car, and sports cars almost always come with high performance summer tires.
