Wheel/tire combos

I believe that there are three factory wheel/tire combinations offered for the LR3. Two 18" versions and one 19". My question is are they all interchangeable? Are offsets, bolt circles and outside diameters the same, or close enough to the same to be able to switch sets around?

They are interchangeable. The owners manual also lists a 17in option but, I don't see as to how that would clear the rotors if you currently have 18's or 19's. Given a choice, go for the 18's, you have more tire options.
