Don't underestimate how easily the balance can be thrown off. Especially with low profile tires and big wheels.

I took mine to a reputable shop recently and they were all amazed how off the rear tire balance was off.

I've got a staggered setup. Anyway, the balance made things very smooth again.

It's scary to read through the different threads on vibrations.

So many good suggestions, so many things found slightly out-of-round or balance, but the vibration always returns


My 2nd BMW started on these vibes a few months ago. Two wheels were a little out of balance....and the brakes have been replaced all round.

No change in vibrations

As can be read in the other thread about this, I am feeling more and more confident that the root of my problem was alignment.

From the factory, the front total toe was almost double the spec. I had one alignment done which improved things, then I borrowed some aligning equipment and let my perfectionism take over. The toe settings are now bang on spec and my steering wheel is centered. The vibrations have calmed down significantly. In fact, I think the residuals are due to the tyres having some uneven wear from the bad factory alignment. Well, that, and the large Diesel engine rumbling away in front of me...
