There have been many posts about tires and Viper performance. Within these posts varying replies regarding replacements for the runflats that come with the SRT 10s. Can someone who has actually replaced their tires advise brand, store and how the car performed comparatively after the runflats have been replaced? When I get my SRT 10 I would like to replace these tires with a lighter, more grip-prone tire. On the C5 Vettes i have owned that came with the runflats I did the same thing. They are nice when you have a nail or other problem but they really dog whatever car they are installed on. Sure appreciate the insight.
