    The 305/75/16 are classed as a true 34'' tyre but it appears we want a taller tyre like this but not so wide. There's a lot of good brands on the market in this size and the difference can be seen below for a web page i pasted, however in a landcruiser with a H box and 4.1 diff the diffence in the 1 inch in revs at 100km is only 67 rpm

    I had a set of the KM2 in 255/85/16 and absolutely loved em. It is true about the little bit of extra height, it pays off once aired down and provide a lot of grip. I had similar findings with the 7.50R16 factory split rims, once aired down they were so grippy. On the highway I had the 255's at about 50psi for efficiency, they worked very well. Definitely like the aspect of them and as far as wide tyres do look cool, I love the traditional 4x4 tyre look

    ^ there a 33.5"

    255/85r16 really is a great tyre off-road tall and narrow

    My 79 is long gone, never did buy another set of tyres was sold with 2 sets of wheels
    35x12r17 of walkerevan bead locks
    And 285/75r16 pro Comp ats on GXL alloys
    The idea was to hold onto the 79 And replace the 285s with the 255 for every day use / touring. Still think for the 79 there a good option

    Yes, with tyre the pressures well kept and conservative throttle, I was getting 10L/100klms combined with the 255's. I miss my rigs. The 105 is souless. It's like a Camry of the 4x4 world. :D
