Wind Noise At Speed
A whistle or roar of wind that grows with speed usually comes from worn door or window seals, a door that does not close tightly, or roof bars and mirrors.
Normal risk
Not a safety issue. Worn seals can also let water in, so check them.
Short answer · Why is there so much wind noise in my car?
Rubber seals around doors and windows harden and shrink with age. A small gap lets air whistle at speed. Doors that are slightly out of alignment, windows that do not fully close, roof bars and damaged mirror housings also create wind noise. Tyre noise can sound similar but changes with the road surface.
Safe checks you can do
- Check windows and sunroofMake sure everything is fully closed.
- Inspect the sealsLook for cracked, flattened or loose rubber.
- Remove roof barsIf fitted, drive once without them.
