I have an Australian delivery, 2004 Td5 Disco Classic with !8"/ 255 wheels. I find that it wanders a little at highway speeds when braking, particularly on uneven surfaces. Also, it seems to be thrown around a bit, also at highway speeds, when on less than even sealed surfaces. I have tried different air pressures in the front wheels, but it does not improve. Is there anyone else who has had this experience or knows of a quick fix. The car has done this from new. I also have a 1999 Disco II with 16" wheels, and it has done 210000 k's and is more positive in the steering on the same roads.
