If you noticed the air escaping between the valve stem and wheel right after filling that is normal (but it can alarm you) as the air trapped between the tube and the tire needs to escape. Let them sit for a while and recheck the air pressure. You may not have a problem.

Also I don't put the valve stems in right away. I fill them at least twice and immediately let the air out to allow the tubes to untwist and settle in before installing the valve stem for the final fill.
