Fitment Question? Forgestar F14's - offset and width?

I spoke to a few great vendors today and got some varying opinions on wheel sizing. I am also lost on tire sizes.

Car: 2007 335xi E90 - Stock Suspension

Needs: F14's in 19's, no rubbing now or when slightly lowered, decent tire wear, same size tire diameter (all wheel drive)

Here's what I have been recommended:

19x8.5 et30 F
19x9.5 et33 R

and

19x8.5 et 35 F
19x10 et 38 R

I am leaning towards the 9.5 rear to decrease understeer. However, I am totally confused on the front offset. I am also very concerned about tire diameter because of the all wheel drive.

Edit:
Vendor is recommending these tires. This would be a 0.2 difference, which is perfect, but will they rub?
19x8.5 et30 F -225/35/19
19x9.5 et33 R - 265/30/19

Those are fine, no rubbing, but wont look like the picture.Those are wider wheels and more aggressive offsets.Besides the obvious that the bmw is M3.

Here is one 335i with 19x9 19x10

Thanks for the reply. I realize mine won't look as aggressive if my goal is no rubbing or fender rolling. I was really just referring to the gunmetal F14's on a black car.

The 19x9 and 19x10's you posted look great, but a little to aggressive for me.

This one looks nice. I am curious if they rub in the front with et32 since I was recommended et30 in the front.

I am trying to steer away from 10" rears because of understeer from being "over staggered."

Will a 225 tire look too stretched on a 8.5? Is their a good guide that recommends tire size to wheel width?

No problem. 8.5 et32 is fine no rubbing. ET32 will give you 2mm more clearance to fender than ET30.Other words et30 will stick out 2mm more than et32.

225/35 on a 8.5 is minor stretch. And its differend depending on tyre brand.

Here you can find photos of 225/35 with 8.5 by using search

So it sounds like 19x8.5 et30 F -225/35/19, 19x9.5 et33 R - 265/30/19 will work well.

I may go 32 et in the front. I live in Colorado and there is almost ways gravel on the roads that gets kicked up and chips your fenders.

Now what about the tire size and stretching? I am looking at Nitto 555's if that matters. They don't have much of a side wall protector.

Edit: didn't see the previous post when I replied.

The Forgestar F14 wheels are a great choice as they're definitely light weight and strong. You can definitely fit the 19x8.5 with a 235/35/19 and the 19x10 with a 265/30/19 or 275/30/19 (depending on the tire brand). Either one of those tire setups will be fine on the XI awd models as the rolling diameter of the tires is within a 1% difference. The offsets of the wheels are typically determined by the experts at Forgestar on 99% of the orders and only about 1% of customers specify the offsets that they want. They’ll make the wheels as flush as possible and guarantee fitment 100% without any rubbing issues!
