I put Dunlop Rovers on my 2001 Escape at 40K. Seemed quiter at first but now, 10K later, I hear a lot of "whiring," especially at 30 and 50 mph. Hard to describe but very faintly like a playing card stuck between the spokes of a bicycle. The noise doesn't seem to come from anywhere in specific as far as I can tell. So I don't think its a wheel bearing. Car steers and handles fine so I don't think it needs realignment [dones 10K ago]. But it is irritating.
Short of changing the tires, any ideas what causes the noise or how to eliminate possible causes other than the tires?
Thanks for any comments.
