I am about to purchase new rubber for my 80. I do some offroad, not much, but have a winch and lockers to get me through anything I will run into. I cannot decide whether I should stick to stock size or bump up to 285s. I am thinking about the REVOS or BFG AT/KOs (despite my bad experience with them on my FJ-62) My concern is that I will decrease acceleration with the larger tires and I think a inaccurate speedo is a pain. I am not willing to recalibrate it to the 285s. As I said, my truck is rarely offroad but I like the look of the 285s. Should I stay stock or bump it up?
