Thanks for your input and help, really appreciate it

Any pics of your setup? I have 245/35/19 and 265/35/19 and I feel I want to go up a notch on both front and rear, I got one front wheel with 255/35/19 to compare and I like the beefy front stance and sidewall profile, has just a little poke which I am fine with.

I want 275/35/19 in the rear as well as I found that the 265/35/19 a bit stretched on the wheel, maybe the Kumho Ecsta may not be the right brand tyre.

Any pics of 255/35/19 and 275/35/19 on H&R Super Sport springs on the F30, not a 4 series as I feels the fenders are a bit different.

I know this was awhile back, but how much was this car lowered? I have an F30 on H&R Sport springs and I am interested in running a similar setup.

Thanks!

I was on Blistein PSS and lowered maybe .75 -1 inch. Hard to remember exactly, but I had about 1 finger gap and plenty of room with that set up.

On a stock suspension, n55 f30. My front stick out a little bit, got my 437m's from a M4

I don't feel like lowering the car but it does look way better. What's the best tire specs?

No rubbing at all but extremely tight in the rear to the point where a tire from a different manufacturer (but same size) might have rubbing issues.

Just an update to my build, still a work in progress, I have a lot of parts that still need to be installed.

I want to add my contribution here, as this thread in particular is what made me go the 437M route. I opted to go with the Ferric Grey version rather than black. Thank you to alohasurftoad for all the help and guidance. Here is my setup:

- Car: 2018 340i xDrive M Performance Edition (Daily Driver)
- Tire Brand: Continental ExtremeContact DWS
- Tire Sizes:235/40/19 (F) 265/35/19 (R)
- Suspension: Eibach Pro-Kit Euro Springs (Part #E10-20-031-05-22) w/ OEM F80 bump stops.

I've been on this setup for about 500 miles now. Sorry, I know, the pictures are crap. I'll work on it.

[SpoolinAddict]

I'm on stock suspension, and not planning on lowering.
My current tire sizes are 255/35/19 & 275/35/19
Looked at the 437m thread but everyone is lowered, is there any way to make these less stick out, without lowering? The rears stick out and fronts also

the only way to make the outer edge of the rim stick out less is by adding negative camber. this will move the upper tire shoulder position inwards as well, but it will affect how the car steers and cause more wear on the inside shoulder and tread.

if you want the tire shoulder to stick out less, without adding negative camber, you need to stretch 235/40/19 up front and lightly stretch 265/35/19 on the rear. the stretch will tuck the tire shoulders in more.

Do you think that will cause the front to rub?

Hi all

I’m new to the forum, so please bear with me.

I can see this mod has been extensively discussed at length but the approach you take partly depends on what look / outcome you are looking for.

Some like their car slammed, almost lowrider or touring car track-like. Some of us want a more subtle tight, autobahn eater look - with - minimal poke, tyre stretch, and a 1-2 fingers arch space with no rubbing. i’m the latter.

My car is a 2015 435d xDrive Gran Coupe. It has the M sport brakes, MTec drilled discs 370mm front, 345mm rear, and BMW adaptive suspension.

Currently fitted with the M442’s, but having seen how heavy these are, upgrading to a lighter set and likely non RFT tyres will make the handling sweeter. I’ve not decided which wheel to go for yet, the M763’s appear much more expensive, moving into BBS FI and OZ Ultraleggera territory, so this may influence the decision on which ones.

So the question is what tyre sizes run best to keep the xDrive happy on 437’s, have the rubber nicely flush with the arches, and remain rub free. I do not intend to alter suspension, by lowering, etc. and wish to avoid using spacers.

After reading through the thread the sensible option seems to be:

xDrive - 235/40/19 & 265/35/19 - Michelins seem to be the poular choice here too

Most of the contributors say this doesn’t look so good on stock suspension, and looks better dropped. From my knowledge ACS, H&R, etc drop the car about 20mm is that correct?

With my adaptive suspension, I believe the car is lower by about 10mm from stock - is that correct?

So has anyone done what I’m after and can share their experience / photos of a car with this set up, or point me to one, as my heads sppinning with so much information after reading multiple threads.

Look forward to your thoughts. Thx

I'd ask in the UK section pal; you'll get answers from those that have done this with the 437Ms

https://f30.bimmerpost.com/forums/fo...412&order=desc

And yes, tyre sizes are right and you'll get a sensible drop with those springs mentioned

I'm toying with a set of 437Ms myself once Spring comes around for my RWD F31 and I'll probably keep my 18" 405Ms for winters and sell the 397s on, as they weigh a lot compared to the 405Ms and 437Ms!

But I'll probably go 245/35 and 265/35 for tyres with my F31 being RWD

hey, did you ever throw those 245/40 on the front? and did you have m sport suspension or standard?

I put 245/40 and 265/35 Mercedes-spec (only Mercedes and Porsche in these sizes) ps4s's on my RWD which is currently sitting at stock height.

I have the m sport suspension and deciding whether to pull trigger on h&r sport springs or not... would love to get them on, but will be a no go for me if it rubs

Long term update (30k miles)

Front 19x8.5 ET30 245/40R19
Rear 19x10 ET45 275/35R19

Michelin Pilot Sport 4S
Vorsteiner V-FF 112

245/40/19 and 275/35/19 has worked flawlessly over 30,000 miles. This is with zero modifications, stock ride height (MPeformance/Track Handling/MPPSK).

Have a bunch of parts here that I still need to install but I'm quite happy with how things are looking. I am thinking about swapping over to an even wider setup when I upgrade the turbo but will do some modifications in order to do that.

This setups works great but few things to consider.
You MUST go with the exact tire (has to be 8.5" front and 10" rear) otherwise you might run into issues (especially on the rear).
You might get rubbing if you turn the wheel all the way to either side.

nice car and setup, but why did you post in a thread for Black 437M wheels?

Sorry I must of posted in the wrong thread, I thought I was posting on the thread on wheel fitments

[JabariTribe1990]

Better late than never...
Bridgestone 265/35/19R, 245/35/19F lowered on KW V2.
I would like to go lower however, the roads of Kuwait are not ideal for low cars.

Hey all, after thorough research, I also decided to pull the trigger. Bought 437M Shadow off a M4 and slapped on fresh new Michelin PS4S. Went with 235/40R19 and 265/35R19.

I have a slight issue, for some reason when I am reversing if I turn the wheel, my front driver side tire is rubbing slightly. Is anyone else getting this issue. I'm on stock M sport suspension.

I also noticed that my driver front tire is like 0.5" approx. closer to the front bumper compared to my passenger side front tire. is there something wrong with my alignment? Any help is appreciated. Can post pics if need.

the 0.5" forward caster on the drivers side is most likely why it is rubbing.

[dreamwithinz]

Hey alohasurftoad appreciate the response. Is there anything I can do to help fix this. Is it safe to be running this or should I get coilovers and drop the car for negative camber.

Is your car alignment within spec? If not, an alignment can tell you a lot. Although you may not be able to specically adjust caster with oem arms.

You can lower with coils but eibach 5-22 springs w/f80 bumpstops would be sufficient.
