05 HiLux Wheels and tyres

I'm about to update to a new 05 Hilux SR 4WD and I'm after some wheel/tyre advice. Does anyone know the max tyre size that will fit this model without having to opt for wheel arch flares and what wheel offset is required. I intend on raising the suspension an inch or two via aftermarket springs and shocks. My last HiLux had 265/75R16 tyres on 16 x 7 Prado rims which fit perfectly without the need for flares. This combo would be big enough but I don"t know if they'll fit the new Lux...
