As mentioned, 235 mm wide, sidewall is 75% of width (so 176.25 mm), and 16 inch rim.
So the tire height is the rim size plus two sidewalls (16 inches + 352.50 mm), or roughly 29.9 inches. Also as mentioned, this is an "on paper" measurement and actual tires may vary by make and model.
The "pretty much standard" lifted KJ tire size is 245/75r16
. They may have minor rubbing but it would be very minor and very easily remedied (hammering the pinch weld, usually)
Some also do with 265/70r16 but the added width may cause issues. You can also go down to 255/70r16, which are a bit shorter than the 245 but have more width and may still rub.
I always liked the idea of the pizza cutter 215/85s, which are kinda popular on Rovers. But being tall and skinny, they are usually hard to find and expensive and E rated (which would ride really stiff on the KJ).
