215/60/16 Tyres

Hi

Im a new pajero io/pinin owner from the UK, Im complelty new to mitsubishi and 4x4 (as of yesterday) after coming from ford fiestas. 

My question is one that looks like it has been asked many times so please dont get angry.

I have steel wheels and 215/60/16 tyres, I wasnt sure if the 65 profile is just on alloys and i have 60 on the steels due to different off sets etc. Ideally I would like to put some 215/70 cooper discoverer AT3 without lifting it. Would I get a 70 under the suspension or would I be better sticking with a 65?

hopefull these pics work just showing the clearance of an 80% good 215/60/16 road tyre on the steel wheels
