Ready to pull the trigger but wanted to receive confirmation these numbers will work

2016 535 x drive M Sport
I like the concave look for the rear and have read that 1% difference will not confuse the x drive system. Like the wider look in the back

BC Forged KL11 Wheels for
- Front: 19x9.5
- Rear: 19x10.5
- Finish: Brushed Black is their gunmetal look

- BC Forged Center Caps BC-Forged-Monoblock-KL11-Wheels-ed

Michelin Pilot Sport 4S Tires
- Front: 255/40/19
- Rear: 285/35/19

Should I just play it safe and go square setup?
Thanks in advance

It's a 0.4% difference, you good. I'd be more concerned about the offsets.

Also unless you want the rear stretched, I would go 295 or 305/30. I put 285s on my 10.5 wide rear and am looking to change them out

Run flats the car came with are 245/40/19 all around
Is this the recommended measurements from Germany?

I guess I'm just having a hard time trying to find the safety buffer here; because I do prefer the concave look.

245/40/19 or 245/45/18 are the OEM tire specs yes. What safety are you worried about? As a lot of post previously stated, just stay under 1% difference between front and back and you'll be fine. Deviating from OEM circumference just affects the speedo/odometer, not much else.

I get 0.655%, I think the 295s go better with the 255s, did you check your rims offsets?

I think my calcs are correct.
