That hum, roar, or whine from your tyres is more than just irritating — it can signal a real problem. Here's how to diagnose tyre noise and what to do about it.
Some level of road noise is normal. The sound of rubber rolling on tarmac is unavoidable. But when tyre noise becomes noticeably louder, changes character, or appears suddenly, it's worth investigating — both for comfort and for safety.
Types of Tyre Noise
- Humming that increases with speed: Usually indicates uneven tyre wear or a wheel bearing issue. If it changes tone when you gently swerve side to side at motorway speed, the wheel bearing is more likely the cause.
- Roaring or rumbling: Uneven wear, often caused by wheel imbalance (cupping/scalloping pattern).
- Whining at a consistent speed: Could be tyre-related or drivetrain. Check tyre wear first.
- Thumping or knocking: A flat spot on the tyre (often caused by hard braking or sitting stationary for extended periods) or a wheel imbalance.
- Hissing or sighing: If continuous, this is likely a slow puncture. Check tyre pressure immediately.
Diagnosing the Source
Determining whether noise comes from a specific wheel is useful. Drive on a clear road at around 50mph and listen. Then gently steer slightly to both sides — if the noise changes, it indicates load shifting to or from a wheel, which can help identify the culprit.
Solutions
- Uneven wear → tyre replacement, plus identify the cause (pressure, alignment, balance)
- Cupping/scalloping → rebalance the wheel; if the pattern is deep, replacement is needed
- Flat spot → in mild cases, the tyre can round out after a few miles of driving at normal speeds; severe flat spots require replacement
- Slow puncture → inspect and repair or replace
For persistent or unexplained tyre noise, booking a mobile tyre check is worthwhile. Our technicians can inspect all four tyres and identify the cause quickly.
