255/40/19 + 285/35/19 or 295/35/19?

Hi guys,

I have G30 540ix. I'm getting 19" wheels -> 19/8.5 ET 25 front and 19/10 ET41 back. I'm planning to go up from 245/275 and planned 255/295 (better grip - I run fairly big power). But some people told me to rather stick with 255/285s as its closer to 245/275 stock.

Now reason why I lean towards 255/295 is that they are 1mm closer in diameter (circumference). And being an xDrive I was told closer is better.

See here:
255/295s -> the backs are 1.25mm taller
255/285s -> the backs are 2.25mm smaller

This means 255/295 is closer in size than 255/285 by 1mm. However, it makes it also so that the backs are larger than fronts unlike stock xDrive where 245/275 on 19s have backs smaller by 1.75mm (here).

What do you guys recommend and why? THANKS A TON! :thumsup:
