I still have the stock BFG's and they're great in the snow. I had to pull my sisters Toyota minivan out of a snow drift yesterday. The driveway had not been plowed, and there was about a foot of snow. I hooked up some chains and forgot to put it in 4 low. Even in 4 high, I couldn't feel the extra weight of her van. There wasn't any wheel spin at all, she just dug in and pulled like a champ. I did have about a foot of snow on the bed cover but no other weight back there. I pulled the van about 30' and it basically slid on top of the snow. I was, and still am very impressed. What a beast!
