I'm looking for your opinions on what you think is the best snow and ice tire for your FJ40. I have a 71 40 that currently has BFG Mud Terrains, 33/12.50/15 and they really suck in the snow and ice. I've heard going narrower to something like 33/9.50/15 will improve my situation. I know the rearend of the 40 is very light. I tried two 5 gallon Jerry cans full of gas behind the bench seat, but still not happy with traction. What tire and size would you recommend.
