I'd strongly rercommend to not play with different dimension tyres than those recommended by the vehicle's manufacturer on any vehicle with such complex electronic managements... all those systems were calibrated from factory for standard dimension tyres and exceeding that will mix up the whole management and nothing will work 100% OK anymore, you might gain ONLY few inches of ground clearance and ruin other more important capabilities of the vehicle which will be just a bit taller but less responsive ... that's a fact

ALL MY ADVICES ARE BASED ON MY OWN KNOWLEDGE AND MY WAY OF UNDERSTANDING THE DESCRIPTION AND OPERATION OF SYSTEMS... I'M NOT A LAND ROVER TRAINED SPECIALIST JUST AN ADDICTED ENTHUSIAST.
