I replaced the OEMs with Bridgestone Driveguard runflats. I did NOT have any issues with the Goodyear's (re punctures/flats) EXCEPT that they wore out by 32K miles, even with regular rotations. I can't fit a spare in the back due to always carrying stuff, so these were the best choice. The Driveguards are overall better (except a little choppy over uneven bumpy roads due to stiff sidewalls), but my experience showed a pretty substantial range hit that has not recovered in about 10K miles--even inflating up to 44 PSI made little difference. A 10% hit is the general rule with these tires and that's been my experience.
