I just purchased my first 300 touring I love this car, but the wheels that came with it are the 17 inch non chrome wheels. I just found these wheels on ebay from a guy thats near me, but I dont know if he has it listed wrong or what http://cgi.ebay.com/ebaymotors/ws/eB...TODAY.m238.lVIit says it came off a 07 300, but the bolt pattern is 5 x 4.50 or 5 x 114.3. will these fit on my car? if not what exactly am I looking for? Above all the correct bolt pattern is bolt pattern: 5 x 4.53 or 5 x 115 correct? but what offset should I be looking for? say for 17,18,20 inch wheels. for 18s is the correct wheel bolt pattern: 5 x 4.53 or 5 x 115 with an offset of 24? Thanks
