It was the rear tyres! I had a vibration through the steering wheel at speed. I swapped the front wheels to the back and it went away. I then swapped them back and had the tyes rebalanced a total of 3 times and still had vibrations. I then had new front tyes fitted. Still vibrations. I then put new tyes on the rear and the problem is now solved. I never would of thought it was the rear wheels! Only after a quick google and statement posted on a tyre fitting web site that I actually thought there might be something in it. Hopefully this will help people in the future. Im not sure how the tags work so I've add every possibility.
