I damaged my runflats setting them at 30 psi because any imperfection on the pavement would impact directly on the wall support of the tire. 30 is definitely too low for a runflat, but i run my pilot sport plus at 29 front and 31 rear COLD! Remember that at highway speeds the heat inflates the tires up to 2 or 3 psi. Great handling, great steering feel and 7 series ride quality!
