I'm just saying you should be happy to have summer tires instead of all seasons from factory and use them during summer, and swap them with winter tire set during winter. This is what we are (legally) required to do in an increasing number of countries in Europe, for obvious security reason.

We should never compromise with security.

Tires size is not only defined by the size of the rims, and I don't think any of the cars you mentionned are using same tire size as the F15 (expecially RF with the same width).
Also, I don't think you can compare X5 handling, especially in corners, with cars like Jeep Grand Cherokee. Concerning max speed or acceleration, we are not comparing the same class of vehicle here. BMW has totally different objectives with the X5 comparing to Mercedes and Jeep in terms of performance, and tires must meet theses requirements and still provide enough security (braking distance).

Mercedes Benz offers 20" all season tires on the ML, GL, and the GLK. A 20" wheel looks so much better than a 19". Maybe its a run flat issue and no tire manufacturer makes a 20: run flat all season tire. I could care less about run flats.

They do have a 20" winter set up as stated earlier in the thread, and BMW uses run flats only, so no 20" all season options out there.

That said, I agree about winter temps and don't even think all seasons handle that very well in cold climates. I would go with a winter setup.
