When I take the jump up to 35's, I'm pretty sure that I will also switch to two separate sets of tires. One for summer, one for winter.
There are two real choices in my mind:
#1. All Terrains - probably the BFG AT/KO.
#2. A dedicated winter tire. I stumbled across one that's available in 35X12.5R16
I know that on road, the dedicated winter tire will outperform the AT - I just don't know how it will work in deeper snow. I've been very pleased with the siped MT's I ran last winter in terms of off road performance...but I don't know how much of that is due to the siping, and how much is due to the void space between the lugs helping them to clear lots of snow.
Some folks also suggest an MT that's studded, but I'm not at all sure that they will work as well as the first two choices. I know that Hankook makes an MT that's pinned for studs.
I know that there are lots of guys here who have had good success with the BFG AT's for winter wheeling, and I've driven them off road in the winter too (on a one ton). Is there anyone that can compare them to a dedicated winter tire in terms of off road performance? Or even a studded MT?
