Shakey shakes?

[Netstar]

Ok, I had some vibration through the steering wheel at around 60-70 for quite a little while, but i knew the front tyres were almost dead and put it down to un-even wear. I've had 2 new front tyres, balancing and tracking done AND IT'S ****** WORSE!

Now, I just thought this morning that I could have lost a weight on the drive home. This happened to me last tyre change, but I left the house in the dark this morning and didnt take my car, so I didn't check for a missing weight.

The guy did tell me theres a slight buckle on the one alloy, but the balancing should take care of it. Is this right?

I'll check for a missing weight when I get home, just wondering though, what if thats not it?

What other cause could there be?

Thanks,

Matt

It will be a balancing issue for sure.

I have had a few problems with the 'highstreet' fitters getting the balancing right - took a few goes. One thing you may need to check is that the 'heavy' part of the tyre (where the red dot is) is on the opposite to the heavy part of the wheel (usually the valve) - I've had a few where it just needed the tyre rotating slightly on the rim and re-balancing.

Some of the less qualified fitters don't remove the old weights before re-balancing and just add more weights to balance. You then get an over-weighted whell which will cause vibrations at higher speeds.....happened to me. Went to a more reputable tyre dealer and they laughed when they seen the amount of weights the previous clown had stuck to the wheel

When the garage is balancing the wheels, they should, if they're any good, be using a 5 stud flange plate on the machine, not a centering sleeve which IMO, isn't ideal.

By mounting the wheel on to the 5 stud plate, you reduce the error of the operator not aligning the wheel correctly as when using a cone. Less room for mistake, better centering of the wheel and a better balance .
