Hi everybody :-)

I am considering a used set of 647M 19 inch wheels for my G31. Just to try something new and the price is fair.

As far as I can tell, these wheels are originally for G32. The tires are 245/45 and 275/40.

The settings in my idrive will not let me choose this size for rear wheels. It seems 275/35 is the standard.

My question is, will this size of tire mess up the registered speed on the speedometer and the distance registered when driving?

Thank you in advance.

So from the aspect ratio they will be 18" rims on a staggered setup?
the 275/35 will be on 19" rims, and you can change this in the iDrive menu to te correct size.
Also, you need to check they will clear the brake calipers if you have M Sport.

Thank you for the link.

The rims I’m looking at are 19 niches. So according to the link, the size I am looking at is not among the correct sizes for a G31.

In the iDrive menu I do not see a way to change it to this either.

The wheels I am looking at are exactly like these.
