Nissan 370z / All Season tires possible?

wooya21

Hi, everyone.

I'm looking very close at 370z Thouring w/o Sport. Pack. for my wife.
(she wanted Mini Cooper S, but that's another long story)

My only concern, besides the money I have to pay, is that
it SNOWS A LOT in Iowa.

I heard that 370z's summer tires don't have much traction on snow/ice.
But I'm not sure (or able) to have separate set of snow tires and changing those for winter time.

Can I have all season tires in 370z?
Or is it crazy to have all season tires?

Both I and my wife is not much into drifting, speeding or making sharp corners.

In sum, tell me if all season tires are reasonable enough;
and if so, what options do I have?
