the lower the offer the further away for the brakes it will be
30 offset will literally be touching the outer edge of the arch with the tyre. Your standards wheels are 55 offset which are quite close to the strut/brake assembly
with a 8.5 wide wheel your smallest tyre will be a 235 wide which may just poke out of the arch at a offset of 30, with an offset of 44 you should be fine. Now problem being is that to not mess up your speedo too much, it will have to be a 235/35/18 tyre. Not only are they very expensive but the ride will be very harsh due to near enough no tyre left to cushion the ride. If you also have bad roads it will knacker your wheel in next to no time being so low profile.
