The biggest / tallest tyres you can fit on a standard height freelander is 205/80/16, how ever it's likely that these will rub very slightly on full steering lock, but only slightly.
If you plan on fitting a lift kit in the near future then these would provide a good bit of lift and should cancel out the rubbing issues.
I MUST stress the importance of having a full 4wheel alignment test done as soon you have fitted any lift kit. It is almost certain everything will out of sync and the freebie will handle like a bus on ice.
FYI I would only lift by 1.5inch/40mm, from experience this setup works really and reduces strain on other areas of drive train etc in comparision to a 2inch/50mm lift, others may disagree, but having run both setups on several freelanders i prefer the 40mm lift.
