No, you can still choose "staggered summer runflats" in the build for a 2025 that gets you the 8"/8.5" with 225/255 setup (it also includes option code 840 which is increased top speed limiter value). It looks like now it is a no cost option for 2025 too. It was $600 last year on my M340i build.

You’re right. Odd thing is all of the cars I saw had the square setup equipped. Any recs on which tire size?

I had 245/40/19 all around on my 19×8 wheels on my 21 m340. The car felt floaty and sloppy around turns. The tires were dws 06+. This time around l did 235/40/19 dws06+ on my 24 m340 with 12mm spacers all around and it's perfect 👌.

There’s not nearly enough grip. I looked at all the other stock in my area (Orange county, CA) and they all seem to have the 225 square setup. It looks like in 2025 the staggered setup requires the $2400 performance cooling and tire package which none of the cars seem to have optioned.

I’ve decided to upgrade the tires right away and save these stock tires for when I have to return my lease.

Anyways, after looking through this whole thread I’m deciding between Continental DWS06 plus or Michelin Pilot Sport 4s in one of 2 sizes.

245/35/19 or
235/40/19.

I’m leaning towards the 245/35/19. Anyone think I should go with the 235 or all good? Would rather go with the wider tire.

Choose 235, 245 causes too much tire flex on 8” wheel. It reduces handling and is not suitable. 235 is optimal tire size for our 8” wheels.

Car looks amazing. Ride height is perfect. You are on lowering springs correct? If so which ones?

Thank you! I have m adaptive suspension paired with the Dinan lowering springs and supplemental ride and handling kit. 12mm spacers all around and the 235/40/19 tires on the 19x8 squared. Feel free to check out my youtube channel as well!
