I just replaced my standard sport 18 inch wheels/tires from my 545i with Velocity CSL 19 inch and General 245/275 tires. The front wheels were 7 pounds lighter each and the rear were 5.5 pounds lighter each. Compared to the heavier brand tire I had on, each tire I got is 5 pounds lighter. Weighed them all personally. So basically this is approximately 45 pounds lighter mass to spin.
I noticed a signifigant improvement in ride quality, acceleration and gas mileage. I have to say this is the best bang for the buck modification. Not to mention it looks amazing. I went with hyperblack Velocity CSL's. Will put up pictures. I am new here by the way!

Ride quality improvement is most likely due to the non-runflats. ![Cool](https://5series.net/forums/images/smilies/cool.gif)

Steve Dinan told me there are 2 ways to make your car feel smoother. Reduce your unsprung rotating mass, or make your car as heavy as an old cadillac. Just think of it as getting a medicine ball thrown at you while your walking. The heavier the ball is, the more its going to through you off.
