That is the measurement of the width
255(width in mm)x85(height measured in percentage of width)x16(rim)
255/25.4(mm to in. conversion)x.85=8.53"x2=17.07"+16"(for rim)=33.07" tire height
My preference is for ARB, you have control unlike the TT or Detroit. On when you want them to be and off when you don't, you get to decide not the locker. If you can only afford to do one then absolutely do the rear. It's the front locker with stock parts, i.e. axles, that can be most susceptible to breaking components.
Hope this helps
