Precision wheel and tire balance is key to a smooth ride.
Today we had a client visit us with their Z4 M Roadster. His complaint was that after installing his summer wheels and tires, there was a horrible vibration in the steering wheel when driving at highway speeds…..
He drove it for a few weeks thinking it would improve, but it didn’t .
Suspecting a wheel balance issue, We removed all the wheels and spun them up on our computer controlled wheel balancer.
Sure enough, all wheels were showing out of balance. One was slightly bent.
We removed all existing weights and re-balanced all of the wheels.Then reinstalled the wheels onto the vehicle and torqued the wheel bolts to specification…135NM
The bend in one of the rims was very slight, and even though it balanced correctly, it may still prove to be an issue..
