At the kickoff, the balls were inflated to the point that the cloth cover was completely taught with no wrinkles on any of the seams. This is also what the manual says.

When we inflated our ball, everyone thought that it would break well before it reached full inflation. However, the ball reached the proper size without any problems. We were even able to press on it a small amount without it breaking. I've seen a lot of pics on CD lately with people that seem to have under inflated balls. To be blunt, don't be shy about inflating those balls!
