How can I soften the ride of 18" run flats?
I just ordered a 2013 X1 sDrive x-line, which comes with 18" run flats. I love the look of the 18" wheels but the ride seemed noticeably more harsh than the 17". Can anyone suggest:
1. A more compliant run-flat tire than what BMW gives
2. A good non-run-flat tire to replace the run-flats
3. Any other suggestions to address the harshness
I live in LA and have no need for winter tires.
