    That's true, I always forget about that! The length of a kilometre changes.

    Thanks for all the comments, good info. I don't think I will go any larger than 245/75/16 or 215/85/16...at the most for now. Maybe there's more value in a rear diff lock than the extra clearance!

    Had 245/75's on ours (300tdi/auto).
    Only thing that used to bug me a bit was getting going when towing our Jayco camper. Felt almost dead until it started to build boost at around 1800 RPM. Learnt to live with it.
    Great apart from that, and probably a fuel pump tweak would have improved things but I never got round to it before I sold it.

    My 300tdi 110 defender with zf4hp22 auto and disco transfer case drives 265/75/16 fine, only down side is box hunts between lock up in an 80km zone.

    I have the above tyres (265/75-16) on a 300TDI disco with ManWell. 2500RPM is the magic mark, returning about 10.5 to low 11's. Towed a renta-car trailer back from syd with a 121 Metro on board and returned 11.2/100.
