Help! As I was pulling into town tonight on my way home from work, I started noticing a rhythmic “thumping” noise that got faster if I sped up and slower if I slowed down - sort of like the noise of a flat tire, but my tires aren’t flat. No change in the way the car drives. Any ideas? Thanks- Toni
What you might be hearing is a belt seperation in one of the tires.
Each tire has a belt that runs directly under the tread. If the rubber part of tire seperates from this belt, a void is created between the rubber part of the tire and the belt. So each time the tire rotates to where the void comes in contact with the road, it can make this type of noise.
