Mini Cooper Run Flat Tires and Performance

I submitted a question about the run flat tire. The road noise was excessive. I changed tires to Michelins instead of the Parrelli’s, it is like a new car. Noise is down and the ride has improved significately. Also performance was not what I thought it should be and I put a K&N air filter element on it and it really scats now.

Thanks for the input. Im sure others will benefit from it.

I doubt an air filter change would add much, if any, performance unless the replaced unit was filthy.
