As some of you may have read, I had some probems with 4 Goodyear F1's since fitting them to my car, awful vibration through the whole car, but mainly at the rear. I had the wheels balanced a number of times over the last 2 months, swapped front to rear etc... No difference 40mph upwards, it was awful, a real rollercoaster ride ! The car when into Audi as I thought it must be a suspension issue, they changed the wheels and confirmed it was the tyres, I drove the car with a different set of wheels - Perfect - It seems the tyres were out of shape. After a mornings work on the phone to Goodyear and the tyre shop, they agreed to change the tyres and offered me 4 Conti Sportcontact, I thought they would be contact sport 2, but they fitted 3's as above. The feel of the car is vasly different to how it drove on the F1's, quieter, more composed, it justs sits on the road so much better than it ever has before.. Has anyone else had any problems with F1's, and has anyone had any experiance of the Continential ? I'm confident my next set of tyres will be Continential. Cheers.
