Believe it or not those are 34s, look small there!! I know what you mean by no traction with offroad tires in snow. I have to run 4hi if I drive this in the winter just to get enough traction to go anywhere. Bias ply tires dont help much in winter but they are great for the mud and offroad around here!
Id be willing to bet its the copy of windows from Microsoft Website thats giving you problems. Ive never had luck with them but thats just my luck!
