I posted a little while back about a severe rear wheel noise I was experiencing on my '08 Patriot. One response suggested a "noisy tire". This made the most sense to me, as I have experienced this on a different car. The problem, however, is that I have driven about 2500 miles since my first report of the problem, and the noise seems to be getting worse. My other experience with a noisy tire ended about 500 miles after it started. Can a tire be "noisy" for this many miles, or is there possibly something else here? I hesitate taking it to the dealer, as they usually have a long wait getting the car back. I can deal with the tire issue as long as that's all it is. Again, I have no noticeable loss of steering, braking, handling, etc. I only have 19000 miles on these tires.
