Hey, long time no speak. I just had an odd question kinda...I rotated my tires yesterday, all torq'd to spec and what not. After rotation, I now notice that there is a very small bumping in my ride while coasting about 25 mph. Never when accelersting, no shake in the wheel, just that and the slight sound of this bump, cleverly disguised as regular road noise. As in, you can barely hear it. Would you say it's just the rear tread adapting to the front, or do I have a problem here?
