snow plow tires

I liked my BFG rugged trail LT's on my 2500..... until they were almost down to half tread. That is when they got hard and slick. At that point, they were bad in the rain and sucked in the snow unless I dropped them to 30 psi. That made them a little better in the snow. I really like my Nitto's... or would plural of Nitto be Nittoes? Lol
