The BMW 3-Series has been around in one form or another since the mid 70s; according to BMW’s naming conventions, the 2012 328i was powered by a 2.8L inline 6 that put out 231 hp, delivering 18 mpg city/28 mpg highway with plenty of power and performance. The 2010 328i offered the kind of comfort, engineering and quality that BMW owners have come to expect, with coupe, sedan and wagon body styles (and also BMW’s xDrive AWD system as an option).
For a sporty sedan like the 2012 BMW 328i xDrive, your best bet will probably be premium all season tires that can offer long wear, a quiet, comfortable ride, year-round traction and responsive handling. Have a look at tires like the Bridgestone Potenza S001 RFT (with run-flat technology), Kumho Ecsta PS31, Falken Ziex ZE950 A/S and Bridgestone DriveGuard Plus (65k mile warranty). For more spirited driving, there’s summer and ultra high performance tire options like the Pirelli Cinturato P7 and Bridgestone Turanza EL300A RFT. Just bear in mind that UHP and summer tires are designed for warmer temperatures; their soft rubber compound will stiffen and lose traction in colder weather and should not be used when temps are below about 45 degrees F.
