I just put on some metzeler Sportec M1s. Took it for a spin and heard noise starting at around 10mph on up. Has anyone else noticed this is a noisy tire, or do I have some other problem. I had some tires on my car once that sounded similar, thats why I suspect the tire. I sure hope its not a bearing making the noise. Could a shop f-up a bearing while changing and balancing the tire?
