If you're the owner of a 2007-2012 BMW 3 Series, then odds are you probably do not have a spare tire. Therefore, you may be considering run-flat winter / snow tires to help you in case you experience a tire blowout during the winter months. Besides providing great wintertime traction, run-flat tires are designed for the colder months to maintain temporary vehicle mobility even after air loss.
For the 2012-2013 winter season, the following 225/45R17 run-flat options are my top choices based on customer feedback and my experience with moderating several BMW internet forums:
- Bridgestone Blizzak LM-25 RFT
- Dunlop SP Winter Sport 3D DSST RunOnFlat
- Michelin Primacy Alpin PA3 ZP
Before deciding on one of these three options for your BMW, consider the differences between them.
- The Michelin Primacy Alpin PA3 ZP gives up a bit of deep snow traction compared to the Bridgestone Blizzak LM-25 RFT and Dunlop SP Winter Sport 3D DSST RunOnFlat. If you're in an area where you frequently drive on loose, unpacked snow, you'd want to consider either the Bridgestone or Dunlop option.
- Do you live in an area that receives a light amount of snow and are willing to give up some snow capability for better dry road handling? Then take a look at the Michelin Primacy Alpin PA3 ZP.
- For more moderate to heavy snow areas, I would lean towards the Bridgestone Blizzak LM-25 RFT or Dunlop Winter Sport 3D DSST RunOnFlat. I would expect the Blizzak LM-25 RFT to perform slightly better on snow and ice than the Dunlop. Otherwise, these two run-flat winter / snow tires are very comparable to one another.
