Hi all,
I usually fill up my tires to 37psi. Every morning before I set off to work I see a pressure of about 34psi on three tires however the right front is always a little lower. In about 3-4 weeks of filling it, the right front shows a cold tire pressure of about 27psi.
I drive on the highway for about 20 mins to reach work, by then the three tires show a warm tire pressure of about 37-38 psi and the right front is at around 30psi.

So do I have a slow puncture? Do I need to get it fixed?
I live in the bay area in California. Please give me some recommendations for a good tire shop nearby. I also have Costco membership.

Thanks!
