IMO run flat tires are not a good value due to the higher cost and they don't always perform as they should. The stiff sidewalls should reduce tire rollover for better handling but some conventional tires also have stiff sidewalls. RFs weigh more than like size conventional tires so there is an increase in unsprung weight which reduces cornering performance.
