Don't buy the Pirelli Pzer MS Nero. I have them and they are noisy and rough riding. The Michelin Sport are far better. I have had three sets of the Michelin Sports on corvettes and they are great. The Pirelli's will also form cups and then the noise really sucks. Run flat Michelins are much better than any other run flat.

You must be getting your mileage calculation from the happy meter (on-board computer). When I calculate it manually I average about 15.5 overall with 17.6 the best I have ever gotten. I drive 70-75 most of the time.
