Balancing S Line Alloys

[JamieH2304]

Can anyone confirm; is there a special way to balance S line 18" alloy wheels from a 2008 A6?

I have slight vibration through the cabin when up to motorway speed. Getting them balanced before has improved things or perhaps at best, changed the resonance.

I have read that when balancing, the centring cone should be fixed to the inside face of the wheel hub as this is the only machined centre. The outside centre is purely formed by casting. Is this true? Not keen on rocking up to my local tyre fitters, telling him how to do his job armed with fiction.

Cheers

You're probably best asking around to find a good, experienced independent tyre fitter and explaining the issue to them. They can have a good look at the wheel for buckles or damage/warping to the face of the disc (or even play in a wheel bearing).

I can't answer your question directly but do see vibrations misdiagnosed quite often. Is there any brake noise/vibration/pulsing?

Thanks for the response.

I've solved it. Flipped the rears over to the front last night and went for a drive. Steering wheel had a noticable wobble right from the off so it was immedaitely clear I had a buckled wheel not curable by getting the wheels balanced.

Took a guess at which side it was on, swapped it with the spare (proper spec alloy wheel) and was away without the wobble.

Did forget to remove the locking wheelnut key before driving off but found it again 30 mintues later, in heavy rain I've not seen in a long time. Still a result!

Good stuff; if you were down south I could recommend a man to fix the wheel but I don't know anyone near you.

FWIW, I had my S8 wheels fixed as three were out of round. Within two months one was out of round again

I've now decided to buy new TUV approved aftermarket wheels and see how long they last!

Pay attention the load rating. I recently ordered some rated @ 755kg should be more than enough for my car. While I was looking I saw wheels rated as low as 400kg.
