Wives tail. The difference is neglible and no different than running tires with 30psi vice 35psi. Don't listen to all the marketing hype.
"Tuned" to BMW means there is a cunt hair difference. The tell you it is a big deal because they have agreements with tire OEM's to encourage run flat replacements. Many people have dumped run flats and the only side affect was an extremely better ride and handling.
