What height should my Navara Be.......

Hello All

Before i purchased my ute someone has replaced the factory wheels and tyres and fitted 15" rims with 235/75/15 tyres.
This gives the ute what i think is a very low look.
Anyway i have taken the measurements and was hoping someone could help me out by telling me how high there ute is
From the ground to the top of the tyre i have 690mm and from the ground to the bottom of the flare i have 840mm
These are taken from the FRONT of my ute.

My ute is a single cab DX model.

I will see what the results are to see if replacing the wheel will raise the vehicle at all

if you put a 265/75 it will raise the height.(not by much tho) shouldnt have any problems fitting it.

going to the tyre size joshy said the 265/75/R16,
that tyre is 70mm bigger so it should raise your ute about 35mm
