Hi All,

I'm planning to purchase some rims for my F30 335i MSports, the sizes are 19x9.5 et22, 19x10.5 et34.

Does anyone know if there would need to be modifications done to the car (fender rolling or camber) with these sizes?

Thanks!

Setup is a bit agressive. You will have to put negative camber to make it fit which mean, new tires every 6 months if you drive the car like the way it should be driven haha

Btw, do you happen to know what is a good size that wouldn't require camber or modifications?

typical aftermarket 19's: 19x8.5 ET35ish with 235/40/19 or 245/35/19 front.
19x9.5 or 10 ET40-45ish with 265/35/19 or 275/30/19 rear. 235/265 or 245/275

Thanks for the info! Do you know if there is any way to get 19x9.5 et22, 19x10.5 et34 these sizing to fit on the car without rubbing?

you'll need to lower you car, add a camber kit to increase negative camber, stretch narrower tires and possibly fender rolling. the front will be poking way out and rub at full lock. please review this thread and maybe post questions or private message members here.

Those wheels were likely taken off of an F8x car. Those cars have wider fenders to accommodate more aggressive specs like these. These would be very aggressive on an F3x car. As mentioned, fender modification, stretched tire and a good amount of negative camber would be required.

This is what 19x8.5 ET35 and 19x9.5 ET45 looks like. No modifications required.

So i ended up getting the following wheel sizes

19x8.5 +30
19x10 +45

I should be fine right? What tire size would you recommend with these wheels. I like the low profile look.

235/40/19F, 265/35/19R is what I would get, however if your car is lowered, you could do 235 or 245/35/19F, 275/30/19R for "lower profile looks". your speedo will read higher than actual, if you care. if your car is not lowered the 1st set up is better for reducing fenderwell gap, whereas the 2nd setup will increase it.

Ah okay, that makes sense, thanks for the advice! My car will be lowered with Dinan springs so it will only lower it about 3/4" in the front and back so pretty moderate. I tried your suggested tire size on the link below to get a feel for it and I think I like this setup 235/35/19F, 275/30/19R. But why would the speedometer read higher than actual with this setup?

from the factory F30,1,2,3,6 come with 26"ish diameter. running a smaller diameter causes the speedo to read higher than actual, conversely a larger diameter reads lower than actual. fyi bmw speedo has an error built in that reads higher than actual to begin with so running a smaller diameter than 26" will exacerbate the error. larger or smaller diameter tires than oem affect the odometer as well. these errors are small so most people dont care about it, but i do

[beeyar]

Really? I would think BMW would be smart enough to calculate based on whatever setup you have instead of hard coded to only use factory as default. When you go a mile on your car it should know when you hit a mile, at least the GPS on the car knows...

[beeyar]

Oh and one last question. For daily driving and also somewhat performance, which tires would you recommend?

I've run several tire setup. A good tire for me, daily driving, good performance but good life range, is the Toyo proxes 4.

[alohasurftoad]

if you do not want to break the bank the best bang for your buck summer tires

1) continental extremecontact sport
2) hankook ventus v12 evo2

if you can spend more

1) michelin pilot sport 4s
2) pirelli pzero pz4

Nice, let me do some research on each of them. Did you go with the run flats? Also, looking at the wheel and tire thread you posted lkstaack 10:59 PM 01-15-2018 is on Dinan spring as well with similar wheel size as you suggested that you would go with 235/40, 265/35 and like you said the fender to wheel gap is less, which I kind of like. Since my springs does not lower my car that much I think the low profile look will cause a greater wheel fender gap and might not be how I expect. I might have to go with the one Yu suggested above. There should be no rubbing issues correct ?

[alohasurftoad]

if you want performance and ride you'll have to omit runflat. i bought a scissors jack, 17mm lug socket and breaker bar, portable 12v air compressor and tire plug kit for an emergency. if you have a big rip in the tire i'm not sure how well a runflat works for that anyway.

no rubbing with 235/40 265/35, fill fenderwell gap, better ride & impact protection, fixes bmw factory speedo error.

f30jetsfan has 235/40 265/35. kfc2 has 235/35 275/30. lstaack has 245/35 265/35, 25.8" 26.3", staggered diameters causing slight forward rake if you don't mind it

I see what you mean with the staggered diameter setup on Istaack's car. My question is, does this staggered setup affect the ride quality negatively in any way or is it purely just looks?

Also, with the 235/40 in the front, since the tire diameter is larger this will also create less fender gap in the front compared to Istaack's setup (245/35) right? Because after looking at his fender gap between the front and back some more, I feel like his rear is slightly less than his front. Or it could just be all in my head

245/35 is 3.4" sidewall, 265/35 is 3.7". there is be a difference in front and rear ride due to sidewall height but i'm not sure if you can "feel" it.

re lstaack, front gap is more than the rear gap. if he had adjustable coils, lowered the front only, reducing the front gap to match the rear it'd prolly look more even.

from a profile view 235/40 has less gap than 245/35, however the 245/35 shoulder is 5mm closer(to the fender arch) and sidewall more vertical which helps to close the gap difference somewhat.

Interesting. I think I get what you mean. So basically you’re saying the Istaack setup for the front wheels will have less of a fender gap than the 235/40 even though the diameter is larger for the 235/40?

it's possible, but i think the 235/40 will still reduce the fender gap more than the 245/35 in lkstaack's case

the more flush the shoulder of the tire is to the fender arch, vertically as well as laterally, via being taller, wider, bulging "flusher", etc reduces fenderwell gap.

conversely the if the tire is narrower, shorter, stretched, tucked, etc increases it.
