Hi guys

I could put the hand on a great deal! It's the bmw 763M

Spec :
19x9 + 29 wrap in 245-35-19
19x10 + 40 wrap in 265-35-19

Tire : Michelin pilot cup 2.

It's to put on a F30 X drive 2018. Car will be lowered on bilstein coilover.

Would this fit without any negative camber and does it create any problems for the X drive system?

Thank!

Ideally wouldnt you want an xdrive to have the same size wheels all around not staggered setup?

[alohasurftoad]

rear wheels fit, front wheels will poke slightly and depending on the tire size and brand, there is a possibility of the outer shoulder may rub the fenderwell liner at full lock. the front and rear tire diameters are 25.8"/26.3" a difference of 1.9%. general rule of thumb is not to exceed a diameter difference of 1%, though i believe i've read peeps with a 1.2% difference on x-drive.

you'll need to run 235/40/19F, 265/35/19R or 245/35/19F, 285/30/19R. replace either the front tires or rear tires but it won't work as is, AFAIK.

these are the same fitments of m3/m4 wheels and you need to be lowered and run slightly stretched tires to fit it. look for threads on the 437m (not rep) to see how they fit and what tires other members have put on there.

Is there a way you could run these square at 255 some how? what offisets would you need to have?

The front wheel wrap in 255 will be to wide for a f30

[AddictedTo///M]

Please post pictures if you make this happen. Those are my favorite wheels and would love to have these on my F30 (xDrive). Would square 19x9 245's work?

you could run 4x 19x9 +29 front wheels with 255/35/19 but there is a possibility of the the outer shoulder of the front tire rubbing the front fenderwell liner at full lock.

or you could run 255/35/19 rear and reduce the front to 245/35/19. 0.8% outer diameter difference is still ok for xdrive and front should not rub fenderwell liner at full lock.

19x9 with 245/35 square will work.

you could still run staggered wheels/tires on your xdrive if you desired. for tire sizes, 235/40, 265/35 or 245/35, 285/30

Thanks for this.

I love these rims. I want to run 255 square on my 2014 435iX . It I lower my car (not sure yet on the suspension) and it I run some negative camber plates, will these fit and still rub with negative camber?

What offset in the front +29 and will this be the same for the rear as well.

Thanks

you'll need four 19x9 +29 fronts. both fronts and rear will be poking slightly with 255/35/19. depending on the tire brand/model, there is a possibility of the front tire shoulder rubbing the fenderwell liner(at stock negative camber).

as you lower your car, negative camber increases with lowering and toe will change. depending on how low you go, if you are able to remain within spec on toe and negative camber during alignment, you may not need camber plates. having a camber plates would be safe, though.

adding additional negative camber should mitigate any rubbing issues at front and rear

FWIW changing to 245/35/19(instead of 255/35) square or 245/35/19 front, 255/35/19 rear will eliminate any potential rubbing up front while still retaining tire diameter tolerances for x-drive

Do you have any pictures of some rims? With this setup at all? Really appreciate all this info. Is a 245/255 rear stagger going to be almost as good as a 255 square for feel? My car feels great with my snows on, so much more balanced - even though they are 225 square.

although 245/255 is slightly less overall front grip than 255, being 10mm narrower, 0.2" shorter and 1-2 lbs lighter will quicken the turn in and improve the steering response and feel. bmw x-drives are rwd bias so this would make sense, as well.

from the sister website. this person upgraded front 19x8 442m from 225s to 245s. old was 225/40, 255/35, new 245/35, 255/35

Hi where did you buy these from please?

Any final pics you could post?

Thanks

F30 xDrive comes staggered from factory.

225/40R19 and 255/35R19.

I found a good deal on some m2 wheels 8.5x18 etc 27, and 9x18 et 29. When I put the specs into an online offset calculator it looks like maybe the fronts could squeeze into my '19 f36 rwd, but the rears would really be sticking out (~24mm) and likely not fit. Is anyone able to confirm I'm thinking correctly?

M2 wheels do not come in that size, so they're probably budget quality, cast replicas made in china.

you can use 245/40/18+255/40/18. poking but not excessively.

personally, i'm not a fan of reps and rather get a set of decent aftermarket flow form in a bit higher offsets or used genuine M.

Thanks! They're genuine 640m. Perhaps I have the specs wrong.

ahh ok, 640M is a cast "winter" wheel for M cars. 0.5" wider and at 25.5/27.5lbs, slightly heavier than 397, 400M, 441M. nothing special about'em except having something different than most.
