Hi everybody :-)

I posted this yesterday on the general board, bit figured it is more suited here.

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. Even though the seller has been running them on a G31.

The tires are 245/45 and 275/40 on these wheels

The settings in my idrive will not let me choose this size for rear wheels. It seems 275/35 is the standard size for 19 inch rims..

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

The wheels I am looking at are exactly like these.

Thank you in advance.
