Posted this in xi forum but this one tends to get a lot more traffic...

I currently own a 2007 335xi sedan and I am very close to ordering varrstoen es5 19x9.5 et 22 front and 19x10.5 et 22 rear. I am not lowered yet but intend to this summer on sonictuning s3 coils. I was wondering if there is a way to make these offsets work on my car without to much fender work, but I am open to anything.

Also questioning what size tires would be best for this setup also in order to get within the 1% range. (wanna stay away from 225 in the front) Any help or pictures of this setup on an xi would be greatly appreciated.

If you don't want to use 225 front, then you are limited to 235/35/19 and 265/30/19 tyres. You should be able to fit these with front and rear fenders rolled and some added negative camber, maybe need some cutting from the fender bumper bracket at rear.

Same specs and tyre sizes.

ES5 wheels, but narrower tyres you can't use these tyre sizes.

Had almost the exact setup on my car. I was running 9.5 et25 and 10.5 et22. Made it fit with 225/35 and 255/30. I think you could definitely work with a 235 up front but I dunno if i would wanna go up to a 265 in the rear as i was rubbing a little before i even dropped with the 255. I rolled the rear and ran -2.5 camber once I got coils and was golden.

Okay thanks a lot, from the sound of it, it'll probably be best if I just go with 225/35 255/30 then. This is the best setup for xi with 225 upfront correct?

Also as I don't plan to lower the car as soon as I put these on, will I have clearance issues before lowering?

With stock camber you might run into some rubbing in the rear on larger dips but nothing too major. I ran the same setup in the rear on my 335i for a few weeks and if im thinking correctly the xi sits up quite a bit higher than the RWD car

**edit: just saw you are in an E90 as well so you may still be able to run the 235 and 265.

Came across this setup, 225/40/19 front 255/35/19 rear, will that be too big of a side wall to run on the wheel specs I am looking to run? I just want to get as close of a running diameter as possible between front and rear.

This is the ideal stagger for our cars, and is the one BMW recommends for 19" wheels. There are plenty of others that work, and even some which are closer in overall diameter (such as 235/275, as I have on mine).

Additionally, PLEASE, I beg of you, lower the car first, it will look utterly ridiculous at stock height with such aggressive rims. Like a monster truck, I kid you not.

That will have the effect of gearing down your car (slowing acceleration, potentially increasing top speed, throwing your speedo way out, and generally putting more strain on the drivetrain). Not recommended if you ask me.

I don't understand why exactly that would happen? For 225/40/19 front 255/35/19 rear the front diameter is still greater then the rear (662.6mm vs. 661.1mm) which on many threads is said to be needed and only a 0.23% difference which I find to be much better then 0.71% difference that would result from 225/35/19 and 255/30/19.

The gearing down is something new to me so if you could explain that would be greatly appreciated.

[Aashenfox]

Yes, the ratio is fine.

Regarding the gearing issue...think of a bicycle if it helps. We change gears on a bicycle to affect how far we travel per pedal rotation.

A bicycle wheel has a set circumference. For the sake of argument, let's say that we have 1:1 gearing and a driving wheel circumference of 2 meters. So for one rotation of the pedals, the driving wheel rotates once and you travel exactly 2 meters. Now imagine if you swapped the driving wheel for one half the circumference (1m circumference), NOW, for each pedal rotation, you only travel 1 meter, and the effort is much less. Similarly, if you increase the circumference of the wheel to 3 meters, the gearing still ensures that you travel 1 rotation of the wheel for each rotation of the pedals, but now its 3 meters and requires considerably more effort.

If you have a speedometer on the bike, (which is programmed with the stock gear ratio of 1:1), it will expect that for every rotation of the wheel you travel 2 meters, if you reduce or increase that, its calculation will be wrong. Basically, your BMW 'knows' your overall wheel circumference, if you change it, a lot of things that are based on that will be wrong.

If that still doesn't help much, maybe someone else can have a crack at explaining it, but basically, as well as making your speedo radically UNDER-report your speed, it will strain the drivetrain and brakes.

Just used 1010tires as you said and I fully understand now, I didn't realize it was the comparison back to the stock wheels that you were referring too. So i guess it'll be the 225/35/19- 255/30/19

As you already figured it out those sizes have too big diameter and wont fit with those wheels.

Yes the 225/35/19 and 255/30/19 will work at xdrive and don't think you will have any bad issues with rubbing with xdrive height, but it will definitely look funny without lowering. The closest for xdrive would be 225/35/19 and 265/30/19.

Is it okay to use the 225/35/19 - 265/30/19 with the front diameter being slightly smaller then the rear?

I've read in a few post that it is better to avoid this but I do like how closely they match sizes....

I don't see any problem with it and i will use those sizes next summer.
