I decided to pull the trigger on this setup after surfing through this thread. I tried to get a couple of pictures from different angles.
Estroil Blue F30 x OEM 437m Wheels x H&R Sport Springs.
Tire Sizes: 245/35/19 Fronts and 265/35/19 Rears wrapped in brand new Firestone Firehawk Indy 500's.
Alignment: -0.5 degrees of camber up front and -1.5 degrees in the rear. (Within factory specs)
I know I asked about running 245/40 but I wasn't sure if it would rub. If I had to do it again I would definitely put a 245/40 on the front. It would fill in the small gap up front and I am sure it would clear with this drop. The rear is filled in perfectly.

when you put 245/40/19 on front the next round, let us know.

your car is looks epic!
For sure next time around I will get the 245/40 and report back.

Hi there, I need some advice about what tire size to get.

I have some Vorsteiner V-FF 112s (19x8.5" ET30 front 19x10" ET45) coming in Wednesday and I want to order some Michelin PS4S tires.

I am trying to go 245/40/19 front and 275/35/19 rear. I am honestly only worried about the fronts rubbing but I hear depending on the tire, there might be enough clearance.

I am running on the Stock M Adaptive Suspension, my car is a 440i XDrive Coupe with MSport, Track Handling, and MPPSK.

here is 245/45/18(26.7") at ET35 on a lowered F30... https://f30.bimmerpost.com/forums/sh...0&postcount=10. i believe the broader shouldered 245/40/19(26.7") at ET30 will reduce the space where his finger is at, where it will be touching, but since your car is 440xi with m-sport suspension i'm not sure what subtle fenderwell differences there may be. that is why is said IF it rubs, i think it will likely just be grazing it.

this stock susp x-drive gran coupe, rubs at full lock with 235/40/19 at ET29. but he's the only one i've ever read about that rubbed with 235/40/19 ET29. https://f30.bimmerpost.com/forums/sh...&postcount=158
this F30 was rubbing with 245/45/18(26.7") ET31 up front and changed to a tire size 1" shorter. see the difference of 245/45/18(26.7") rear compared to 245/40/18(25.7") front.https://f30.bimmerpost.com/forums/sh...3&postcount=22
Thank you for the quick and very in-depth reply. The issue I have with warping the fender line is that because it has the Track Handling Package, it has vents for the brakes. I will attach a picture for reference and take one in the day time so you can see what I'm talking about. I do not think it's a good idea to mess with those vents in order to avoid rubbing at full lock. Regardless, I believe the F32 should have a tiny bit more clearance than the F30.

https://imgur.com/gallery/Zp4r8Ar

But basically, this is me running 225/40/19s in the front. I was wondering about the guy who had rubbing on his F30. I see he isn't using the Michelin Pilot Sport 4S tires, I picked the sizes mentioned above because the tread width is just short of the actual rims. Tires from differing manufacturers may have the same tire size but they can be spec'd quite differently.

So in the case of the PS4S 245/40/19, it has a tread width of 8.4" vs the actual 8.5" rims. And for the PS4S 275/35/19, it has a tread width of 9.8" vs the 10" rims on the rear. IMO, tread width matching the actual rims is much more important than going with "the widest rubber you can fit" and this is mainly for handling purposes.

I always have the option to downsize to 35/30 vs 40/35 however, I would like the higher sidewall considering I live in the NY area where potholes are quite plentiful. I am sick and tired of playing hide and seek with potholes in Manhattan and my Bridgestone Potenza S001 run flat tires are ridiculously harsh despite having the adaptive M suspension (less harsh than having plain old M suspension).

Another reason is, unfortunately I can't find the link but someone mentioned on these forums that he wished he went with 40/35 sidewalls compared to 35/30 because it would have "filled in the gap".

I go on quite a few spirited drives when I go around the twisty roads in the Poconos so I really do not want to deal with rubbing at all.

Anyone with a F32 + Michelin PS4S tires who can give me some advice?

These are awesome looking and quite simply amazing. Love the color of the car too. Does anyone know if the 437m will fit on a 2014 320i xDrive?

Here is a much better picture of the vents for the brakes.


For those with Track Handling Package F32s, I don't think messing with this is a good idea. You can still roll your fenders however.

I hear you are running 245/40/19s in the front. I was wondering if this is still possible to run with the stock M Adaptive Suspension (without any rubbing). I understand you are on lowering springs. Please correct me if I'm wrong.

I ended up doing 245/35/19 because I couldn't get anyone at all to confirm if 245/40 would fit. But I have thicker tire. It has not rubbed at all. On stock suspension, you can definitely pull off 245/40.

When you say thicker tires, what sort of diameter are we talking. For me it's 26.7". If that clears in the front, I'll have no issues. My rims are coming on Wednesday and I still haven't ordered tires because of this dilemma.

Honestly, I think I'll just order the Michelin PS4S tires today (245/40/19 front 275/35/19 rear). If it fits, great. If not, I'll just return it and go with 35/30 side walls.

Thank you for the quick response and for the reassurance that I needed. On Stock M Adaptive Suspension, I hope these clear.

I'll definitely post an update after I get the tires/wheels fitted for those wanting to do a similar setup. I know most people run the usual 235/35/19 f 265/30/19 r. But depending on the tire manufacturer, you want to match up the tread width to the rim width as much as possible. Never go above, try to be within 0.5" and you will have superior handling to other setups who simply fit the fattest tires they can (which they boast about but in the end it leads to no increase in handling and/or performance).

For people living in the NY area, trust me, your gonna want to go with the biggest side wall possible. You (and your back) will thank me later.

Exactly I like having a thicker sidewall if possible. 40 is the best imo. I did 265/35/19 in the back, not 30. I don't want rubber band tires. The only reason I was concerned was because I am on lowering springs. On stock height you'll have more than enough room around the fender for the bigger tire. Michelin 4s will be the same thickness as my tire which is the firestone firehawk indy 500. They run thicker than they say they do. Next time I need front tires I am going to try 245/40. I didn't get to try it this time because I was in a time crunch and wouldn't be able to return the 245/40 and swap for 245/35 if needed.

Gotcha. Thank you for the update. I'm definitely getting the 245/40/19 front and 275/35/19 rear Michelin PS4S setup. I will post an update when I have the tires installed. I am not in a time crunch persay so I can live with having to return the tires (if they somehow do rub).

Couple more pics of the 285/30 tires on the rear. I think I have room to lower the rear even further if I wanted to and I would probably still not rub.

Appreciate your try and interested in your feedback. I am currently running 245/40/19 19x8.5" ET35 on M adaptive x-drive and my biggest concern would be the clearance from the fender liner, as the current tire already comes very close to it.

Pulled the trigger this weekend and purchased a used set of OEM 437m. They have the stock Michelin pilot super sports 255/35 in front and 275/35 in the rear. Still have not added them to my RWD 435i. I've only found out about some poke that occurs with these rims after purchase lol.

From all the research I've done all this weekend it seems most people are lowered and worry about rub. I will not be lowering my car because I feel it's low enough as is. But wondering what tire size will reduce poke. 245/40 fronts and 265/35 rears? Or 245/35 fronts and 265/35 rears??

Anyone that is not lowered and running these wheels, preferably another 4 series non gran coupe owners please chime in!!!


Thanks in advanced

F32 440i XDrive with MSport/Track Handling Package/MPPSK
Stock ride height with M Adaptive Suspension

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

Michelin Pilot Sport 4S
Vorsteiner V-FF 112s

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.

Could you share a few more pictures? I'm interested to see if you have any poke and how the car looks from a lower camera perspective.

Finally got through the whole thread, but not sure if I have the right answer still. Have a set of OEM 437M's heading my way and drive a 2015 435i GC M Sport. Not lowered and not planning to do so. The consensus seems to be 235/40/19 and 265/35/19 may be best for my situation?

I have a 440 M-Sport Gran Coupe running 255 front 265 rear MPSS (OEM M2 sizes). 235 is too narrow for a 9" rim in my opinion.

Lowered H&R Springs.


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

No rubbing at all on front or rear


Your car looks great! How much camber are you running on the front and back?
