A few questions. Does it seem to wobble or bump? Does the noise change when you go around a bend? Does the pitch change with the speed of the car? To me, a flat tire sounds more like a humming/roaring sound than a whine/whistle sound.
If it is wobbling or bumping, you likely need a new tire over there. A steel belt inside the tire (under the tread) has broken and the tire has developed a bump in it.
If the noise changes as you go around bends and changes with speed, and sounds more like a roaring/humming sound, then you probably need a wheel bearing -or- hub assembly. Generally, when I have a bad wheel bearing, I change the whole hub assembly. Because to me fixing a part with 187,000 miles on it to save maybe $40.00 just does not make sense.
Here is a guide on checking the tires:

Here is a YouTube video on checking for broken belts:

Also, feel free to take lots of pictures and post them here. I will gladly look and see what I can see. Make sure to get good, detailed, close up shots from as many angles as you can.
