I have a question that maybe someone here can answer.I have a 2008 335i w/sport package and it seems that I am going slower than most and it feels like I am not going the same speed as on the speed odometer(slower).Are these cars calibrated with the larger wheels or is it the same rolling mass as the 17in. wheel package.

I traded in a 2008 Vette for this car and in the Vette at 70mph it did feel as if you were going 70mph.

BMW speedo's are a little off. 75 is actually around 70 or something. Do a search and you'll find lots of info.

Thanks for the info,is there a fix for this?I will do a search to see what I can dig up.

This is interesting. No wonder I always seem to be cruising at 80mph.

Does anyone else have input on this?

The overall diameter of the 17" and 18" wheels are almost the same, don't think you could feel the difference.

I dont think the wheels make a difference. I was going 70 on the highway the other day. GPS says 70, but SPEEDO said 75. So it is about 5 MPH off. If you do a search you will find alot of info on this.
