    Default Correct pressure

    How does one determine the correct pressure for tyres on a vehicle. As an example, a set of 265/65x17 BF Goodrich on a Ranger 4x4 d/cab running with 2 adults and no load in the bin. What pressure is correct. Ask 10 people and get 10 opinions

    Even more possible answers here. Theoretical the tire pressure must equal the wheel load over the tyre contact area, what ever that is.

    But it should be in the range of 2 to 2.2 bar

    My 2016 Ranger XLS 4x4 DC.
    265/65/17 KO2's, standard suspension.
    This works for me: 2.4 in the front always, maybe to 2.5 bar when all my kit is loaded.

    Empty bin I run the back 2.3 bar and fully loaded 2.6 bar. In Nelspruit I nearly came short with 2.6 bar in the rear with an empty bin. Thank goodness for the traction control. Okay it was pouring with rain.
    I travel alone, so driver only, no pax.

    Tyres have done 42k km and still 9.5-10.5mm left. Just rotated and these pressures seems to work well for safety, wear, fuel consumption and comfort. That's my first hand experience.
