When driving, I noticed that a slapping sound was coming from my rear passenger-side wheel. The tempo of the slapping sound would accelerate and decelerate as the car's speed increased and decreased.
I replaced my wheel with a spare after reading this article since it suggested that the tire tread might be separating.
After I replaced the wheel, the slapping sound went away. However, I didn't notice any bulges on the wheel that would indicate tread separation.
Could this really be a case of tire tread separation? Or might it be something else?
