The z doesn't come with all season tires because all season tires are mediocre at everything. You get mediocre summer traction and terrible winter traction. I think you're better off with summer tires in winter, knowing that they suck in snow then with the false sense of security you have from 'all season' tires. All season tires work decently in snow on a underpowered fwd car with thin tires. On the z the improved traction you get on snow is marginal at best when compared to a summer tire. Hence, let the car come with summer tires, and if you want to drive it in winter/on snow, you'll get a set of winters, instead of throwing some mediocre tires on it so that the overall driving experience is diminished.
