I recommend whenever one hears a strange noise, or his bike behaves improperly, he should quickly inspect the bike to discover the source of the problem.
Since we only have two wheels to balance upon, I inspect all components of a wheel whenever I need to remove it.
In particular, I always inspect the following items.
Wheel Bearings
Hub Integrity
Replace/Tighten Spokes
Rim Integrity
Brake Drum/Caliper
Brake Shoes/Pads
Tire Tread
Tire Pressure
When changing a tire I also inspect the following items.
Spokes protruding through spoke nipples
Inner Tube Integrity
Rim Strip Integrity
Spud
