It's not critical, but you do need to change them soon. I'd say another 3,000-4,000 miles. That wear pattern isn't too bad for that much mileage. It's really more than most people get out of them actually. That wear pattern looks like the tires were underinflated. Unless the alignment is really off, that's usually what happens. The inner shoulder shows more wear than the center also.
Tire pressure should be around 35-36psi. I think Nissan recommends 35psi.
