i don't think you can do four rears 4x 19x10 +40 with 265/35/19 as the inside of the front tires may contact struts, spring perch or inner fender.

Thank you so much for assisting me alohasurftoad! I pulled the trigger for a pair for these haha.. Now to find tires... I found someone selling 225/40/19 front and 255/35/19 rear. Is that okay? I got a -0.23%. But the 235 - 265 probably better looking right? hahas

You can do OEM staggered sizes of 225/40+255/35, however the tires will be stretched, especially up front.

Got cha. Is stretched tires bad?
I realized its quite hard to find runflats that are 235 / 265. Got any recommendations?

considering 255 sits squarely on 9". to put a 225 on 9" you'll be pulling the tire beads 30mm(1-3/16") wider apart to seat them on the rim. it'll be easy to curb and can get nicked easily from steep walled potholes.

since 275 sits squarely on 10", putting a 255 on 10" will be stretching 20mm

other sizes combinations that will work with x-drive are: 245/35+285/30, 245/35+275/30, 255/35+265/35. while 245/40+275/35 is compatible for x-drive, +29 offset and 26.7" front tire diameter may cause the outer shoulder to contact the fenderwell liner during full lock and/or compressed suspension turns, so i don't recommend it for 437M offsets.

Hey guys .... been a while since I have been on here (since my E90 days).

Has any one ran the M3 reps on a 330 x-drive with H&R Sport Springs? Looking at this set up from my wife. My guess is I would need to get (4) of the fronts and keep it square.

Me! I was running square with M3 fronts on all four corners with stock 255/35/19 fitment. I'm lowered on H&R sport springs and found I was rubbing quite a bit on dips/bumps and they tramlined. Needed new rubber last week, so I downsized to 245/35/19 all around. Rubbing issues are gone, much less tramlining, and slightly less poke from the fender edges.

Thought about going back to staggered with either 255s or 265s in the rear, but I like being able to rotate my tires and balanced dynamics is more important to me than aesthetics or just straight line speed.

You have any pic of this setup with the car lower?

Are you rubbing in the front or rear?

Not at all. The fronts were definitely rubbing with the 255/35/19s. Haven't had a single issue since going down to 245/35/19s.

It's just one of many CF trunk lip spoilers off amazon.

Here's my setup, OEM 437m with Conti DWS06 tires, 255/35/19 in the front and 265/35/19 in the rear. Springs are Eibach Prokit with OEM F8x bump stops.

Major shoutouts to alohasurftoad for the countless of PMs that I have went through with him to go over tires spec for my xDrive with these wheels. I learned so much about the transfer case and diameter of tires from this man.

Another shoutout goes to FaRKle! for talking to me about bumpstops and spring rates etc. After playing around with cars and suspensions for 15 years or so I never thought bump stops were important.

Without these 2 guys I would've probably made major mistakes that would have been very costly!

There has been no issues so far, no rubbing on full lock turns going forward or in reverse. I did rub one time on stock suspension going straight over a speed bump, but if I go on an angle, theres no problems.

The ride is very close to what percychow describes in his thread.

This turned out to be exactly what I was looking for and I felt like I owe it to this thread and to the members I mentioned above to post my pic.

Sorry for the dirty car, I need a detail badly!

DUDE LOVE IT!!!!!
Now you got me wanting 19s!

Looks great, that lighting really showcases the beauty of the OEM 437M machined chrome finish, something the replicas do not capture.
Still loving these wheels on my car a year later.

I got 295s in the back. Sticks out a bit which i show in my video.

@alohasurftoad

Any reason why you didn't recommend 235/35/19+275/30/19? Michelin p4s - for xdrive f32 coupe - car is lowered on dinan springs and bumpstops

Although both front and rear diameters are equal, both are 25.5". Smaller diameter, shorter sidewall equals worse ride, impact protection, increased speedo/odometer error. it'll look better if you're slammed. So, that's my reason for not recommending. It will work, if you don't mind what i consider cons, though.

Oh wow, didn't know of increased speedo/odo

Is it much though?

I don't mind about impact protection - mainly aesthetics and ride

And to recap, with my mods, you would suggest
235/40+265/35

the speedo reads high from the factory. a smaller than oem diameter will increase the error little higher and it will accrue more mileage than actual. it's not very much but exists nevertheless. lots of peeps running smaller, just not my cup of tea.

my purely subjective viewpoint is 235/35-275/30 will look better if the car is lowered to where the fenderwell lip is right at or just a tick higher than top of the tires. i'm not sure where the dinan drop would be, though. i understand if you like that lower profiled look on the tire.

235/40-265/35 is my favorite size combo for x-drives with 19's but the selection of brands/models/categories is limited.
