I dont think so, but is there any way to fit the 4 tires only in the car between the back and passenger seat? Looks to me 2-3 max, but I'd like to avoid having to have my wife follow my in the FX twice a year to rotate the tires on and off.

Unrelated - would you go 225 all the way around on the Blizzaks as seems to be the TR recommendation?

 

Narrower tires are better in the snow. I'd even consider going a little narrower than that on a second set of rims. That way, you can do the wheel / tire swap at home instead of always going to a shop to swap the tires.
I personally put a lot of trust in TR, they have alot of expertise.

 

+1 def get a second set of rims...well worth not having to drive back and forth every time. i have a set of oem 18s im looking to get rid of if you are interested (shameless plug!)

 

Nope. Unless you hold one and drive its not going to work too well.

 

I've fit all 4 stock rims/tires in my car...unbolt the passenger seat for the rear two, and the front two go in the hatch.

You can't do this with 285 19's though...

 

Nope, just talking about the tires here, not rims.

 

tires alone or tires w/ rims in them takes the same amount of space. Nice suggestion up there unbolting the passenger seat, it's only like 4 bolts and a few wires, takes literally 5 minutes, you should consider that option.
