Tire flat in storage, something to worry about?

Well, my car is going to be in storage for another couple months. I went out to check on it today, and one of my tires is pretty darn low on air. (It's patched, so I knew it would leak a little)

Is that something to worry about? Will it ruin the tire with it low on air pressure?

Just wait till I insure it again and drive it slow to my buddies house that has an air compressor and fill it up there?

Thanks!
