I have a very tinny sound coming from my driver side front wheel well. I don't quite know if I'd describe it as a rattling or a brushing. It is directly related to tire rotation speed, not rpm. It happens in a straight line, no matter whether I'm accelerating, coasting, or decelerating. I've inspected my wheel well and the tire for signs of rubbing, but I can't see any. I've had no rubbing with these tires. I've had these tires for 2 months, and I've only noticed this sound today. It seems something goes wrong every week with this truck. Please help! This sounds worries me a lot. Thanks in advance..
