Noises

Humming noise from the tires

A steady hum that changes with tire type and road surface, rather than with engine RPM, usually comes from the tires themselves - either their tread design or uneven wear.

Symptoms

  • Humming or droning noise that varies with road surface
  • Present at speed but not at idle or when stopped
  • May be present on all tires or worse from one specific tire
  • Volume changes noticeably between smooth and rough pavement

Likely causes

  • CommonNormal tread noise from an aggressive or all-terrain tire designSome tires are simply louder by design, especially those meant for off-road or all-weather use.
  • CommonUneven or cupped tire wearIrregular wear patterns create noise that a healthy, evenly worn tire wouldn't.
  • PossibleTires nearing the end of their tread lifeWorn-down tread can sometimes hum differently than fresh tread.
  • PossibleMismatched tire types or brands on the same vehicleDifferent tread designs on different corners can create inconsistent noise.
  • PossibleUnderlying alignment or suspension issue causing uneven wearThe wear causing the hum may have a root cause worth addressing.

What to do

  1. Check the tread pattern and note if your tires are an aggressive all-terrain or off-road style, which are simply louder by design.
  2. Run your hand across the tread of each tire to feel for uneven wear patterns like cupping or feathering.
  3. Have the tires inspected and rotated, since rotating can sometimes even out the source of the sound and helps a technician assess wear patterns.
  4. Check tire pressure across all four tires, since incorrect pressure can contribute to uneven wear and noise over time.
  5. Have an alignment check done if tires show uneven wear, since a misalignment can be the root cause.
  6. Compare the noise on different road surfaces (concrete vs. asphalt), since some tire designs are noisier specifically on certain surfaces.
  7. Consider a quieter tire model at your next replacement if road noise is a significant concern for you.
  8. Address uneven wear causes (alignment, suspension) rather than just tolerating the noise, since it also affects tire lifespan.

Tools and parts

  • Tire tread depth gauge
  • Tire pressure gauge

When to call a pro

If tire inspection shows uneven wear, have an alignment shop check and correct the underlying cause in addition to any tire replacement.
