Run-flats typically have low rolling resistance and less grip; comparable regular tires have higher rolling resistance and higher grip. The latter weigh less and feel quicker as well.

How about switching to 235 wide tires at the same time as removing the run flats. Has anyone put 235 wide on the 18" sport like rims?
To keep the same diameter you will need to go to 255/40 on an 18" wheel, although it would be close with a 235. Keep in mind however that wider is not necessarily better for performance, unless you happen to just like the look.
