Hi there.
With the 130i, if your car came with oem 17's, then most likely these are style 207m, with the following specs: 5x120 pcd, 7x17 front, 7.5x17 rear, ET47 offset all around. The RFT spec'd for these wheels by BMW were 205/50/r17 front, 225/45/r17 rear. If you want to change wheels and use the RFT tires you've already got, then I suggest you choose an oem BMW wheel with same specs and make sure these wheels are specific to run flat tires.
Hope this helps.
