on a clincher tire, incorrect. Yes, the air exerts force on the rim, but this is exactly balanced out by the opposing force on the rim at the bead. Otherwise the tire would fly off the rim.
on a tubular tire, then correct. The rim does not support pressure loads, so it does get compressed by the tire.
