TIRE PRESSURE DROPS TO 28 OVERNIGHT, BUT NEVER LOWER.

We have a 2008 Buick Lucerne CXL with Vogue tires. The right front tire has been reading low according to the car's pressure censor. It was reading 28, we filled it to about 38, and the next day it was back down to 28 according to the pressure censor. When check manually, it read 28. It seems like there might be a small leak somewhere, but wouldn't the tire continue to lose pressure rather than always dropping down to 28 and staying at that pressure?

If the leak is small, it would drop fast when pressure is high and the leak would slow down after that. If you allow it to sit longer, you would notice the pressure dropping further.
