Hi,

I have a 2005 BMW X5 3.0D.

Whilst driving the steering wheel vibrates slightly from side to side when going over 80km/h or so. Then when i brake at high speed the vibration gets a lot worse.

I know that my tyres need changing as they are very old and they will be changed next week. However is this vibration due to my tyres or is it something else?

Usually i would associate this problem with disc brakes however as it vibrates even when driving and not just braking this surely can not be the discs right?

Please help.

Thanks
