Hi. I have just discovered a strange noise from my car. I only hear it when I drive with one or both of my front windows down, and when the car is moving. The noise is not coming from the engine it self (don't hear it when I rev the engine while standing still). It's a bit difficult to explain the noise in English here, but it sounds like an irregular tik-tika-tik noise. Like something is hanging down and touching the wheels when they rotate. I have checked the wheels but can't see anything wrong. Fitted with 205-50-R15. OK.. not so easy to explain.. but maybe some of you have heard the same noise....

could be your windows knocking against something inside the door, try them half way up and see if you can still hear it.

not to be patronising, but check for stones in your tyres....

I had a terrible noise coming from my wheels the other day - sounded like a puncture or something falling off. It turned out to be a scrap of insulation tape stuck to a wheel and flapping against the wheel arch

have you had your brake pads changed recently? the springs are quite fragile and can become loose leaving the pin guide free to bang around makin noises.give it a look see.

Is it constant in a straight line, if so i've got it too check for stones in the tread tho, cos it got a lot quieter when i did that, still there tho, so i'm thinking either the hydraulic tappets... or.... the power steering belt!!!!!
