245/35/19(25.8")+275/30/19(25.5") is 1.0% and will work on x-drive but since the rear diameter is smaller than the front, you may need to lower the rear a hair to even the gaps.

245/35/19(25.8")+285/30/19(25.7"), 0.08%, is a better size combo for the gaps and more importantly the transfer case

consider 235/40/19(26.4")+265/35/19(26.3"), 0.37%, 5mm taller provides a better ride and 5mm more ground clearance and at your current height, the taller sidewall will reduce your 1 finger gap to virtually zero, giving the illusion that you are lower than you really are. imo this is the best combo.
