Bridgestone Blizzak LM-25 RFT Winter 245/50R17 99H Passenger Tire

Fantastic winter tire especially for rear wheel BMW's. The traction and stopping power on snow is amazing. For the first time, feel confident driving into the mountains during winter w/ a rear wheel drive. Day and night when compared to all season tires, even if compared to front or 4 wheel drives. Tires also handle very well in dry cold winter temperatures. They are smooth and comfortable at interstates speeds and also handle potholes in the city very well; a great benefit given the bad road conditions and aging infrastructure in our area. With a lot of dry road driving, tires definitely do show some wear, but I guess it's a tradeoff for having solid winter weather traction.

There's just not much OEM approved for the Z-4. Between these and the OEM potenza's, quiet, don't follow every little groove in the pavement. Given that the car is not run on a track every weekend, or even ever, these tires make somuch more sense than the OEM. And, heck, this is my ladies car - and, in Portland I hear it rains. And snows maybe once per year. I feel SOOOOO much secure knowing she is driving on these than on the Potenza's. I suspect there are better options if you want to carry a can of fix a flat with you (car came with run flats), but in the RFT options - these win!
