Some of the lowered guys have done 245/35 and 275/35. You'll be fine on stock height at that.

That's probably stock spec. I got my car back in factory spec on the same springs.

I was being a smart-ass but damn if MLev didn’t find (and PM me) some good looking candidates (not on EBay) for around $1400, including a Ferric Gray set. I never think to look past EBay for used wheels, mainly for the convenience of shipping and the Buyer Protection stuff, but apparently I overpaid a bit for my set, even with the new-ish tires.

So yes, even at $1500 a set of clean OEM take-offs makes more economic sense than an $800 set of reps.

Lesson learned

May I ask where you were looking/finding used M437s?

Hi Everyone!

Thought I'd contribute as well. This thread and few others made me pull the trigger on 437Ms.

2018 BMW 340i xDrive - Stock M Adaptive Suspension.

Tire specs are:

Kumho Ecsta PS91
F:235/35/19
R:265/30/19

Very satisfied with the tires!! They are super sticky for the price. However, i do wish i went with a bigger sidewall set up because with my current set the sidewall are very thin. I wanted to go for a little more meaty set-up..

With stock suspension there is no rubbing at all. But... The wheel gap (Mexi-Flush) is really bothering me I did purchase H&R Sport Springs and will have it installed sometime this week. Will update my post again.

[KrampusF30]

Here's my 437M wheels... an absolute steal for $1100 off FB marketplace in Milwaukee with TPMS and rubber, reduced to $825 after I sold the tires.

I am on stock suspension. Tires are Continental Extreme Contact 235/40 and 265/35 which are almost identical for circumference (due to Xdrive). I wanted Michelin Pilot Sport 4S but my dealer said Michelin was really affected by the COVID shutdown.

thanks to the invaluable info in this thread I was able to get dialed in

[perezr10]

How are you guys with Pre-2014 cars handling the TPMS? My tire shop told me that I can't swap the sensors from my 397 wheels to the OEM 437's because they're not compatible. I have a 2013 335i sedan.

Yup, ran into the same issue when I changed from the 441m wheels to the 437m's, I have a 2014 F32 that was giving me the tpms errors. However the tire shop I took it to was able to swap the sensors from my old 441m wheels and it works just fine now.

Thanks to everyone who contributed to this thread but especially alohasurftoad who ultimately swayed me to go & change my order.

Just adding my 435dx (stock height) with the so sexy 437m in OEM M4 MPSS tyre combo.

Time to contribute to the thread. Lowered on Super sport springs, M performance front bumper & painted gloss black lip

Hi guys! I drive a 2017 BMW 440i xdrive coupe and want to change my wheels to 437m staggered rims (19x9 & 19x10). I visited a tire store and they gave me two possible options for this set up, 235/40/19 and 265/35/19 . The other option is 225/40/19 and 255/35/19. I want to know if this is a safe set up and won't mess up my xdrive system or cause any problems to the car. I have stock height no modded springs or lowered.

Hi there
235/40/19 and 265/35/19 should not be a problem.
I've been running that for almost 3 years and approx 80.000km without an issue.

[Shady67]

Lowered on Eibach Pro Kit lowering springs (06-22), 225/40/19s in the front and 255/35/19s in the rear:

Just a little bump for this thread, I have just read a whole bunch and found it very informative. I just picked up a set in Ferric Grey and am hoping to fit the 225/40 and 255/35 combo as I'm running air suspension and shall need as much clearance as possible especially on the inner front as the airbag on my strut protrudes further out than the stock set up.
Hopefully I can pull it off without rubbing the bag as I love the concave OEM look these give. I may see if my tyre shop can fit the run flats from my OEM 442M fronts just for a test fit before dropping £££ on fresh tyres.

[_baz]

Just an update after a test fit today

Pics are with a 5mm spacer up front to help clear the air bag / strut

Stock tyres (275 / 255) will not let me air out completely so will be swapping for 255 / 225

[_baz]

Much better with the 255 on the back and 225 up front

Lowered H&R Springs.


rear 265/35/19 MPSS
front 235/40/19 MPSS

No rubbing at all on front or rear

Looks Amazing! Great work

Where were you able to find a set of squared rims in the 437m's?

Found a seller who bought an extra set for his F80 to go square using the rears so he ended up with 4 fronts that he had no use for.
