How old is the tire? Did the valve stem get changed also when it was torn down for bead sealer?
Old rubber can leak also and you'll never see the leak. Although 10 pounds a week should bubble something up.
I don't know about the states you all live in but around here. Once in a blue moon a story is aired on the news about an accident and recommending to NOT be using tires over 5 years old. I"m not even sure if tire shops even screw around with em anymore. I tried to get a new tube in my motorcycle a few years back and had to buy a tire also. Course, the bike was 10 years old with original tires.
