Well, the tires themselves are identical. They're the same tires. Only the wheels have changed. ("the wheels have been changed to protect the innocent...")

Now, I'm not quite sure the tires remained in their same positions when I had the wheels changed. That might affect the results, but very likely not in a statistically significant way.
