I have recently bought a set of 18" RS6's with Toyo T1R tyres 225/40/18 from Rochford tyres. Whacked em on and took the car for a spin but got a whole load of vibration through the steering wheel from about 40mph upwards, so I took them to a tyre specialist and they took off all four wheels and found that they needed re-balancing but also stated that three out of the four alloys looked buckled (flat spotted)??? and proceeded to show me on the wheel balancing machine how they weren't running straight. At the moment I am facing a long drive on Saturday from Birmingham to Essex for Rochford to have a look at the alloys!!! So my question is has any body else had any problems like this? Could it be that they are buckled or could it be something else? Please help! All comments appreciated. Just to set the record straight I have bought from Rochford before and didn't have one problem.
