    Biggest legal tire size for a disco 4

    Hi there,

    I'm considering changing my rims for my Disco 4 to take a larger size tire. Does anyone know what is the largest legal rim and tire size allowable. Also need to consider that tires will not rub against anything when 4WDing and wheels articulate.

    Thanks

    I run 265 65 18, equates to 32 inch, they just rub on full compression in the rear but it only just touches the plastic inner guard so no issue

    Miffy,

    I run 20" wheels with 275x55r on my D4 31.9"

    The front can rub under compression, but very little.

    31.6 if you want to split hairs so closer to 32 than 31
    275/65/18 is 32.1 so technically 2.1 bigger than standard and therefore technically 0.1 bigger than the legal size increase, the thread is after all named Biggest LEGAL tire size

    Well ok but that's the size Johnson rods site recommends for Disco 3 so maybe they are wrong to sell these with that quote ?? So what size would you recommend that is exactly 32" cos i am right in the process of buying JR 's with the idea of fitting 32" ie; 275/65/r18 ? Cheers

    Just curious why so big. You must have a rear tyre rack as my 265 65 18 has to be stored deflated. 275 is no chance underneath. Horses for courses though. The actual tyre specs on there website will show overall rolling diameter and they do vary a tad for the same size. The standard size of 255 55 19 = 763mm therefore Max = 813mm rolling diameter. 275 = 814mm but you may crack a brand thatís less. 265 = 804., speedo perfect, Look them up. Good luck

    Tyre size and brand is a can of worms. I can only say what I run are 265 65 18 kO2ís and feel bullet proof in them. Iím guessing ( and I donít do this) 275ís may be an advantage for mud rrunning hill climb events. For everyday day touring / dirt roads I believe all round it is overkill and a pain in the proverbial and actually illegal. But yes my 265ís are stored deflated underneath and there may occasionally rub but rarely. 265 60 18 wont do any of the above but are hardly bigger than standard. Cheers
