Oh no another wheels / tyre question for the hilux ...

I've got the dual cab sr. I have fitted ARB flares and Phoenix 17" x 7.5" rims (Toyota aftermarket rims for the Prado) with Cooper ATR 235/70/r17 to keep it within the +15mm total diameter rule - 762mm total diameter.

However, I'd like to put on an OME lift and higher profile tyres on it.

What is the largest overall diameter that has been put on this car? A saw a post from tuff_IFS_hilux that mentioned 265/70/r27 (810mm total diameter). Can ayone comment on whether this diameter rubs? ARB have bfg muddies 265/75/r16 (same diameter) and apparently this does rub but I have spoken to a few shops tat are installing this size 'with no problems'. Can anyone comment on whether the tyre contacts the arches when going over lumps off-road?

Legal issues:
Has anyone tried getting an engineer's report for oversize wheels / tyres? How did you go?
Does anyone know if the national standard bulletin 14 on tyres and suspension (1/2/2006) has been accepted? This seems to allow greater differences than 15mm for off-road or commercial vehicles.

And finally:
Has anyone had a Prado or Hilux (ie electronic type) speedo re-calibrated in or near Melbourne? Could you pl recomend a workshop to do this.

A lot of questions here, my thanks in advance.
