How big can i go on my land rover tires?

i have a 2000 land rover discovery 2 and i was wondering how big can i go on tires and wheels if it is still stock.|||this depends on wether or not your willing to go shaving bits off your fenders. As far as I know on the stock ones the stock wheels are about as big as i'd go. Any bigger and you may get some rubbing problems. Lift it though and trim the fenders and you could get much bigger tires.
