Hello. It is common to lose a small amount of air over time. Usually about a pound or two of pressure a month is normal. If it is leaking faster than that then it amy have something stuck in the tire. In some cases the tire needs to be removed from the wheel to locate the puncture. If there are no punctures then the leak may be in the valve stem. I have also seen some tires leak at the wheel due to wheel imperfections. I would take the tire to a tire shop and have them submerge it in a tank to locate the leak.
