The bearing doesn't rotate at the same ratio.
Actually, it does. It just translates into less LINEAR distance as compared to the outer diameter of the tire. It is turning slower than the outer tire because it is covering much less LINEAR distance as the outer tire in the same period of time. But the ratio of outer tire circumference to bearing circumference is the same. They rotate together in the same circuferential plane.
If you have a record turntable, try this. Put a penny near the center as close to the spindle as you can. Then put a penny in the same spot on the edge of the turntable. Spin it by hand slowly; the pennies stay put, and they don't change location relative to each other. Speed it up--which one flies off first?

huh? maybe i'm not understanding what you said here, but the bearing spins the same as the tire. for every one bearing revolution, you get one tire revolution....

my front wheel bearings lasted 2452 miles and were junk. also when you get the bike up in the air with the weight off of the wheels it may not make any noise if it's the bearings. any play in wheel their bad. put your hand on the axle and roll the wheel and feel for any roughness. you will hear the brake pads draging alittle. you can always pull the cailpers off and roll the wheel .
Be sure you fix the problem before you decide to take it for a spin, safety first!

If you had the back wheel off the ground while on the centerstand, all you need to do is put a jack under the bike in front of the stand. Raise the front a little and the bike will tilt back with the front wheel in the air.

Now, not only does my bike make noise, but my CD player does, too!

It shows how a defect doesn't sound off in symetry with ring rotation. The tire rotates at a different ratio.
