After a few race days my tires are no longer flat, but semi ballooned, even at rest. If you push on them in the middle you can hear the tire trying to stick to the insert and or rim.
If you are running on low-to-medium traction surfaces, the tires actually work better with some ballooning. (It's probably the extra flexibility, rather than the shape, that makes them better.) If running on very high traction surfaces, the flatter tread squirms less, and will probably feel better.
I'm running tires right now that look like they should be on a motorcycle, but they still work great!
