I have been considering going darkside and this information is incredible and amazing. Thank you darksiders. So run flat or not run flat what one should I choose. I think that if I go run flat I need to get a monitoring system for it and I don't want to fork out a whole lot of money on this. As far as the front tire goes does it matter what I run? I am thinking the Avon Cobra's maybe as no one seems super happy with the E3. THANKS!
