19x9.5 Square Setup on F30 X Drive NEED HELP!

Hey guys! I just bought some rims for my F30 335i X drive, they’re squared set of 19x9.5 +35 offset.

Now, I know there’s several threads out there talking about the questions I’m going to ask, but a lot of them are outdated and not very specific. So, to be straight to the point:

- Is it okay to run this setup (19x9.5 +35) squared on an X Drive F30? Main concern is the 9.5’s in the fronts. And yes, I know people have discussed this, but I want the most up to date answer.

- I can’t decide on tire sizes and I’ve come down to these 2 choices: 255/35/19 and 255/30/19. Will one be better than the other or does it not matter? Is there another totally different tire size that’s even better for this setup?

- Yes, I would like to lower my car. Preferably with H&R Sport Springs. But if that’s not possible or will cause rubbing, then Eibach Springs are fine too.

Thanks guys!

9.5 ET35 is pretty aggressive for a F30 with stock suspension. It's going to look pretty goofy if you end up choosing the wrong tire.

255/35/19 is the better size. You could also do 265/35/19, but you'd need more suspension work than just springs to run that.

I doubt you will be able to fit anything close that up front. I have 18x8.5 255 et38 and i'm about 3mm away from hitting the strut. It doesn't rub at all but it has to be right on the edge of both strut and fender. I could maybe add a 2 or 3mm spacer to flush it out a bit, but then I might be running into the fender. I don't really want to run spacers, but I am considering it. The f30 sucks as it can't tuck a lot up front, unless you want to roll the fenders, which I am considering.

I'd like to at least fit a 9" up front. My next car ... stay tuned .. will have 17x10" square...

What kind of suspension work do you propose for wheels of that size?


I want to do about the same as OP. Get a square set of the widest wheels I can fit up front with the least amouunt of camber. I don't like wheel tick or camber that looks broken. It seems that 9 or 9.5 the way to go.

Perfect stance for me is one finger gap above the edge of the contact patch.

So, do you think if I go with 255/35/R19 with just Springs I’ll be fine with no rubbing or hitting the strut? And would you recommend H&R or eibach?

Do you have springs installed?? And do you have 255/35 or 255/30 installed?

Guys it seems as if multiple people are successfully running 245/35’s up front with no rubbing. The guy in that link above did it with H&R Springs. Only difference is that he has 8.5’s and they’re 20’s. Would it still work for me if I used 245/35’s with 9.5’s and 19’s?

If it does work, how bad would the stretch look?

And another question is, whether to get the same tires on all 4 wheels. Should I get something wider for the rears? Such as 265/35 or 275/35?

I would PM .BMW.

He is a great resource very knowledgeable about this sort of thing.

I think those specs would be pretty aggressive for the front. The rears you would be fine.

If you wanted to go square i would look at x9 or x8.5

Yes, lowered on KW v3s. About a finger or slightly less wheel gap.

255/40r18, michelin pilot super sports. Which by the way comes out to the exact 26" in diameter that the car came with from the factory. So I believe it to be the 'most correct' tire size that fits that isn't the skinny joke 225/45/18. However the problem is that (I think) a 9" rim will rub up front, so stuck with 8.5 which makes a bit of a bulge. I am less of a fan of it every day. I want to roll the fenders.............. but I don't think I will. It would be great to fit a 9.5 or a 10 up front.

I wish I could’ve gotten 8.5’s for the front, but I got a squared set of 305 Forged FT107’s in 19x9.5 for very very cheap.... couldn’t pass it up.

SO, if anybody has the FT107’s in 19x8.5’s and wants to trade for two of my 19x9.5’s, Let me know!!

How do you calculate the diameter?? Can it be done using the 1% tire size checker tool? Or is a different one?

I’m curious why you don’t like it as daily? What about 9.5” in the front would be better for daily?

First of all my friend, be advised that you can fit more than a single thought into a single post. Such as this one.

And this one.

See https://tiresize.com/comparison/ & https://tiresize.com/wheel-offset-calculator/ for the numbers.

I'm not aware of anyone running 18 or 19 x 9.5 up front. It's worth a google to see about rolling the fenders and what others have been able to fit.

A 255 tire on an 8.5 bulges out a bit. It looks like a stock tire on a chevy or something. It also always looks low on pressure even north of 40 psi, and there's a lot of bump steer and tramlining. a 245 would fit nicely, but be shorter and have about 1/4" more wheel gap. I won't move the car any lower.

There's a couple members on the board that really know the wheel fitment. One of them has been mentioned above. "alohasurftoad" is another guy who I've read most of his posts in this section.

Yeah I’m new to forums in general and figuring it out. Accidentally treated it like texting. Lol

And yeah I hit up .BMW. and he showed me Googone20’s old F30, which had 19x9.5 all the way around with 255/35’s and he said he experienced no rubbing at all and he’s lowered pretty darn low with coil overs.

It’s motivated me to go ahead and attempt to run this setup with 255/35’s.

So much depends on your overall plan for your car. Is this your daily driver or are you building a track car or something in between? The H&R springs will lower about 1.5" and be much stiffer than stock. Then you have to start talking about struts & shocks to compliment them. It's going to rattle your teeth much more than stock. Make sure that that is what you are signing up for. The Eibach springs are about 10% stiffer than stock. They will lower the front (which is higher than the rear in an x-drive) about 0.8" and the rear about 0.6". So you have some additional strut/shock options with Eibachs since they have more suspension travel. The Dinan springs are supposed to be about 30% stiffer than stock and lower about 0.75" all around. Those were my three choices when I was planning my car.

I've got a daily driver 2015 335i x-drive. My overall goal is a performance street daily driver so I went with Eibach springs, Koni Active Red FSD shocks and H&R Sway bars. The FSD is something that Koni developed with McLaren. It's a performance shock with the piston travel for my x-drive that either hasn't been lowered or has been lowered only slightly. The dual valving really rounds out bumps and potholes that would have been more jarring with the stock setup. It's a pleasure to drive on a long trip and at the same time it's a beast when I hit an on ramp or off ramp.

Something not talked about much, I suspect because the labor price is so high on an F30, are sway bars. The H&R bars take the body roll right out. Turns are really flat. My point is that you need to consider your overall suspension modification goals when you are talking about bigger rubber all the way around. You also start getting into better brakes and more horsepower which I did also. Hope some of this helps you out.

From what I remember in the Track/Autocross section, to fit 9.5" wheels up front you will need closer to ET22 and -2.5 degrees of camber.

Thanks. Appreciate all the info.

I actually successfully got the 255/35's on the 19x9.5's all the way around last night! No rubbing at all and a pretty flush fit. H&R Sport Springs are currently being installed, and I'll update with pictures as soon as they're done.

This was all done with the support and guidance of Googone20, whom I appreciate very much for helping me out.

But based on what you're saying now, I might have to get the upgraded sway bars and shocks. I guess we'll just have to see.

No spacers. Just the wheels and yes they’re all 19x9.5 +35. I’ll be picking up the car in a couple of hours so I can then take some detailed pictures showing the results.

Congrats! Hope you enjoy your mods!
To wet your appetite, here are some photos of the H&R front and rear sway bars. Black bars in photo are the stock sway bars from 2015 335ix that were replaced. Stock bars were light as a feather, almost felt hollow. H&R bars are absolutely heavy & solid. Car corners totally flat now!!!
