Front wheel vibration help

[luke2397]

I've had new wheels and tyres fitted to my E82 125i. Wheels are Fox racing MS007 and tyres are Michelin Pilot Sport 4 DT1 and I've noticed a vibration that seems to be coming from the front wheels. I noticed that the weights had fallen off so I took it back and got them rebalanced but the vibration is still there and it happens at most speeds.
Any ideas would be great
Thanks

Possibly they haven't balanced them right (especially if it's the same place that put them on in the first place and they fell off). Or could be damage to rim (which would also explain the missing weights).
It could be other things too, warped discs, damaged drive shaft, etc but try swapping front for back wheels and see if it makes a difference then at least you'll know if its them.

If there was no vibration before the new wheels and tyres:

1. Check wheel nut tightness.
2. If really concerned, check hub nut tightness or make sure the hub nut locking system hasn't shifted
3. And by far the most likely... they haven't managed to balance them right. It often takes several goes to get properly balanced wheels after new tyres.

4.... and unlikely, your new wheels might not be round. But that should be glaringly obvious on the balancer machine as they whiz round at 70 mph right in-front of your eyes.

I'm also slightly concerned you mentioned drive shaft because when I've started to get my traction control cut in at the most random of times such as I was on the motorway in 6th doing about 60 and even gentle acceleration was making the TCS light flash like crazy on a perfectly dry road

I think most modern ones are more like 15 mph, which is actually better, as at 70 the rim would just be a blur.

Find somewhere who have road force balancing machines to check your tyres and wheels.
