Tire Size for Aodhan AFF7s

I ordered a set of Aodhan AFF7s for my 2022 M340i RWD.

19x8.5J ET35 front
19x9.5J ET35 rear

Not lowered or anything yet.

I am thinking a 15mm spacer in the front, no spacer rear (per a facebook group recommendation)

I've heard an ideal tire setup is 245/40 front and 275/35 for the rear. Anyone here have any concerns with those tire sizes? Would a spacer be needed in the rear?

I ordered mine directly from Aodhan and prefer that. Great customer service and direct shipping.

I have VMR 710 19” with
Front: 8.5 +25 (5mm spacer) 245/40
Rear: 9.5 +33 (no spacer) 275/35

15mm spacer up front, 0 back should be good. If you are lowered you might consider 245/35?

I’m on xdrive and eibach springs so a few things I have to consider. I lowered and got these wheels recently, so far so good.

Initially I tried 12mm spacer front, 5mm rear but I was getting some rubbing up front while turning in reverse.

How is the ride with the Eibach springs? Is it bouncy? Do you have adaptive suspension?

It’s fine tbh. I didn’t notice a huge difference. At the same I went from run flats to non-rft and stock springs to eibach so maybe they cancelled each other out. Yes I have adaptive suspension. As of yesterday I’m trying out SPORT INDIVIDUAL with steering and dampening set to COMFORT so that helps too.

Thanks for the feedback! I ordered direct from Aodhan, they gave me 10% off. Ended up being $989 out the door for the set. I ordered a 15mm for the front and nothing for the back yet. May end up going 5mm in the back. According to "willtheyfit" the fron't may stick out a tiny bit further than the rears, but that's assuming the width is the same front to back from the factory (can anyone confirm?). In a facebook group, a lot of people running these wheels with 15 front, nothing rear.

When I get the wheels and get everything put on, I will update with some pics.

Yeah, I've heard non-run flat tires help with the ride. That's why I ordered my car with such tires.
How long have you been driving on the Eibach springs? No bouncy ride even on Sport suspension setting?
I'm debating between the Eibach and Dinan springs.

Can’t go wrong with either one. A local friend of mine is on Supra wheels + Dinan springs and OEM bump stops, I’m on eibach with OEM bump stops, another friend is about to install H&R springs with Dinan bump stops.

Depends if you wanna play it a little more safe with Dinan or get a little more drop with eibach. Expect it to be a hair bouncier, but tbh I haven’t noticed a difference, but the roads around my house are pretty smooth and I don’t have a long commute.
