What is that advantage of one size tire over the other? They are both roughly a 33", except the 305 is 12. 5 wide and the 285 is 11. 5 wide. Nitto Terra Grappler has both of them in a "E" rated tire now and I will buy one of them but wanted to know the difference. I tow in the winter alot and thought the narrower tire would be better for the snow.
