Every year I am asked by BMW drivers with factory installed run-flat tires if they need to stay with a run-flat option when it comes to purchasing winter / snow tires. There is no stipulation or rule that requires run-flat tires to be reinstalled as the dedicated winter tire choice, however there are some drawbacks you should be aware of before making the switch.
The BMW can make the switch to non-run-flat tires, however, in most cases the vehicle did not come with a spare tire. If you were to decide to make the switch to non-run-flat winter tires, a road hazard would leave you stranded on the side of the road without a spare to put on the car. However, a solutions to this issue is to purchase the Continental ContiComfortKit. The kit is capable of comfortably sealing typical tire punctures making it possible for you to complete the drive home, to work or a tire repair facility. It combines a powerful, high-volume, 12-volt air compressor, integral pressure gauge and a latex liquid tire sealant packaged in a compact, lightweight unit that's easy to store in a vehicle.
Features and Benefits of the Continental ContiComfortKit:
- Braided air hose
- Threaded hose end (more secure than push-on, thumb-lock inflation head)
- 15-foot power cord
- Lighted pressure gauge
- Low-intensity LED supplemental work light
Another option worth considering is purchasing a full-size matching spare tire and wheel. Going this route essentially creates a set of five tires that will last longer than just four. The spare should be integrated into the vehicle's tire rotation from the beginning, as this will "wear out" the spare tire before it "ages out."
The choice to switch to non-run-flat tires for the winter boils down to your comfort level. If having a tire failure and being on the side of the road until road side service arrives or changing a spare on a busy highway are things you could never cope with, then staying with run-flats is probably best for you. If you're confident changing a spare tire in only a matter of minutes or waiting for road side service is not a big deal, then you may be someone who could easily make the switch to a non-run-flat winter tire.
