Question Replace 225/45-18 with 225/50-18

I currently drive a 2015 328GT with a winterset tires 225/50-18. My lease is will be over and will be replacing the GT with a 2017 430 Gran coupe. It will have the M package (19") .. but i believe the base 18" is a 225/45-18. Any idea if I can just use the same winter tire/wheel set for the GC? I have gone through some website to do some calc.. think the speedo meter difference is around 3-4%...

Thanks

225/50 will fit on F30, as long as your wheels has offset around 30-35.

so you think the extra wall height will not be an issue? and the speedo reading?

I am assuming the offset should be ok as the wheels was used in the GT.

As long as the overall diameter is within 3%, you'll be fine.
