[Think-U-R-Mario-Andretti?]

Hi Everyone,
I recently got a 2019 M240 Convertible with the 405 wheel & tire package.
Front: 19 x 7.5 405 M Performance wheel with 225/35/19 HP Run-Flats
Rear: 19 x 8.0 " " 245/30/19 "

I want to fit bigger tires/wheels and switch to non run-flat

GOAL:
Front: 245/35/19 Michelin Pilot Sport S4 Non Run-Flats
Rear: 265/30/19 " "

QUESTION:
1. Has anyone here fit this size tires successfully onto this car?
2. Front - what size wheel 19 x 8.0 or 19 x 8.5 with what Offset Et.?
3. Rear - " 19 x 9.0 or 19 x 9.5 " ?
4. Which Brands have the right combination?

DINAN:
They are offering a BBS CR-I Wheel set
Front: 19 x 8.0 Et. 45 but only 235/35/19 Michelin's
Rear: 19 x 9.0 Et. 48 for 265/30/19
"
AC SCHNITZER
they offer wheels, but don't specify the tire size
Front: 19 x 8.5 Et. 43
Rear: 19 x 9.5 Et. 50

Anyone here who knows if they fit and what wheel brand, size and offset is needed?

Thank you
Matthias

Sounds like you may want to spend some time using the calculator from the 3 series site...

This should answer your questions on what will fit and what offsets will do to clearances.

Your 245 fronts need a minimum 8" wheel
Your 265 rears need a minimum 9" wheel.

Play with the calculator to see what works best for you.
