They are 3-season tents, but in Ohio, Kentucky, Indiana, or Tennesee, it would be rare indeed to need a true 4-season tent. These tents will handle a couple inches of snow load (that's what I know from experience; others may be able to add to that) and are very stable in 25 or 30 mile an hour sustained winds, pitched in the open.

They all have a great deal of mesh, so they won't add warmth - but they will be warmer than sleeping in the open. I've always relied on sleeping bags and pads for warmth; the tent is never more than a windbreak - and that works for the Ohio winter weather I go out in (much below 20 degrees, I stay home.)

If you're looking for true winter gear for extreme situations, none of these tents will be suitable.
