An auto car on a tow dolly?

Why not wait till winter?
Christ I lied to uhaul (works every time) said I was shuffling a couple cars locally and needed the trailer for the weekend. Drove from Ontario to Indiana then up to Pennsylvania and back to Ontario. 4 days and over 2500 miles.
Get it done already.
Can of foam fill for flat tires
Problem with that is I gotta cross over a pass to get there, the pass in winter develops a bunch of this white stuff called snow. If it were a few inches my 4wd would handle it, but nope the pass gets anywhere between 2 and 8 feet at any time. So nope, winter is out of the question.
