I got a hill on my driveway that's covered in snow 6 months out of the year. My 03 F250 with the KOs and open diff goes up easily. My wifes 02 F250 with the KM2s and limited slip needs a run at it. This is in 2 wheel drive and both trucks are 5.4s with 4.10 gears. My 01 F250 7.3 has KOs too with an open 3.73s and it can't get out of its way in 2WD in the winter. Spins way too easy but it is a longer wheelbase and has more weight in front. Also alot more torque. With the other 2 very similar trucks the KO is way better in the snow than the KM2, IMO. :shrug: There are alot worse tires in snow than either of them though.
