One of the best products Giant make are these little washers . I hate the feeling of tightening those little nuts down onto the curved rim surface, I now have these washers on almost all my wheels.

You will always have a gap when the rims starts to curve, this is not where the air seal is made. IF you have a leak, then the valve needs to be tighter pressed into the rim, so that the sealant creates a seal that doesn't move.
