I recently put M sport suspension on my E60 and a set of 19” niche wheels on 30 series tires. The tires are continental extreme contact DW. Unfortunately the car seems to throw the steering wheel around up front a lot due to the harsh suspension and low prod over bumps and it’s kind of annoying. Has anyone else experienced this?

Steering vibrations can be caused by a lot of things, but you said that you recently put on new wheels, so the first thing I'd check is the center bore on those rims. The E60 hub bore needs to be 72.5 mm. If the wheel specs don't match, pick up a set of concentric rings to compensate for the difference.

 

They are the correct size around the hub bore and I have ECS spacers, not sure if these cause the vibrations or not. It’s odd that it does it sometimes and not others. I feel like it’s a steering rack issue.

 

It also feels like I’m feeling ripples in the road even when there aren’t any, very frustrating, this is my 3rd set of tires on the new rims. No difference, I’m looking for anyone who knows a thing or two about the way their car feels on low profiles and can give me feedback.

 

I solved the vibration of my car with 19” wheels only after I balanced all 4 wheels with the spacers on them...
