I performed a pressure check this weekend and the front passenger tire was at 11 psi. I took another reading to verify and confirmed the low pressure reading. I filled the tire up to about 39 psi and checked one hour later and had a reading of 31 psi. Subsequently, I inflated the tire up to 35 psi and it has remained constant at that pressure for the last three days. Could it be that the valve was stuck open and got closed while I was checking the pressure and filling the tire over the weekend? The tires are 1 year old with about 20k miles on them.
Do I have an air leak?

plausible or the bead wasn't seated but reseated. I had this happen on a snow tire once, pulled it out of storage with ~2 PSI, pumped it up, it lost some, pumped it up again, a-ok from then out.
Valve core tools are only a couple bucks, you could try unscrewing and reseating your core.

How long did it take to get to 11 psi? That may be a slow leak.
As for your 8 psi loss...
If that was hot air coming out of an air compressor, and the ambient air temp is cold, that could explain it. Each 10 degrees will move it about 1 psi. Or you could have had a piece of dirt in the valve. Did you check to make sure the valve core isn't loose?

Just had this happen to my Austin-Mini. Last winter and all summer it didn't loose any air from any tires... Then we have a cold snap and I got out the next day and I have 2 rear flat tires... I filled them up to 30 PSI and the next day the same thing. So I filled them to 50 PSI and came out the next day and there was 50 PSI in them. I then let the excess air out and left them with 30 PSI and now they are fine. It has been 3 weeks...
Weird eh?

If you put air in and it holds...you don't have a leak.
If it goes down intermittently, probably frost in the valve. Fill to proper pressure and spit on your finger, place spitball on valve... watch for bubbles. Remove spitball when done.
