I have experience with the ZE-512, and it was a phenomenal tire for the price. Consumer Reports comparo winner. The ZE-912 is the replacement, and should be even better. I've read that it's a couple lbs. heavier than the 512 because they've stiffened it up in the sidewall area (the original's only complaint). Buy them with confidence.
