Don't think I'd consider 2" a BIG lift, but personally I don't think the 245/75's look "all wrong". They fit the wheel wells quite nicely. Yes they rub a tiny bit at full lock, but adjusting the steering stops fixes that.I'm running 215/85 R16s, a taller profile than yours and available in LT if you plan on any rocky off-roading. I like the taller profile while maintaining a narrower tire. I personally don't like anything more than a 235 width unless you have a BIG lift, just looks all wrong and you WILL have additional stresses on the axles with wider tires.
I also used to run 235/85R16s and will probably again, but they make an underpowered rig even slower, and tax your braking a bit more.
I am astounded that the Brits would spec such a wimpy, tiny tire as a 205/80R16 on a vehicle that is otherwise superior to any other of it's size off-road, but they did, and they no doubt sized the brakes and axle loading to that size tire.
Every 4x4 of that era deals with the same issues of small OEM tire size, and EVERYONE puts bigger tires on, but those little 205's are laughable (counting the seconds until someone responds with documented performance of those little tires).
