Hi I have a 2001 BMW 330Ci, and I am looking to get some new rims on it, but I am so clueless when it comes to the world of rims. I have the stock sport package 17" M style wheels on it right now, and my tires are Bridgestone Potenza 225 45R17 91W in the front and in the back I have Bridgestone Potenza 245 40R17 91W. I am looking at rims that are 18x8 in the front and in the back are 18x9. Will these rims fit on the tires, or should I go smaller to the stock 17" size?? Please help me!!!! Thanks !!! You guys are the best!!!
