Search or google the specs of those rims. You need to know the width and offset. Then simply compare to what data is already here in the thread (do some reading).
Based on the tire width, it will all come down to your offset of the rim to know if you will rub somewhere. Judging by the widths you should have plenty of room on the sides. Having said that the tires on the wheels have an aspect ratio of 5 great than stock. So your diameter and circumference will be larger by that amount.
Will it fit? Most likely. They could fill our your arches better if you're not lowered because the overall diameters are larger. You car will be slightly higher off the ground as well. Will your speedometer read wrong? Most definitely.
