OK gang - 04 with 62 k on the clock. Recent trip to Colo and we have LOTS of noise from what I think is front tire. Pull in clutch and noise is same. Happens going straight. I have about 6k on a Bridgestone front. Darkside with about the same on rear. Noise is a whine, much more than I ever noticed before. Steers good, corners OK. Front is not cupped, but edges show pretty good wear. Your thoughts?
