Buying wheels an keep getting recommended crazy different offsets...

Have a 2026 M240i with the square 995m wheels ( all season runflats 225/40/19). 19x8 Stock et is 27 on all 4.

Buying some 19x9.5 and new tires, however I want a white wheel so my options and stock are limited. Rsther than take the one sales guys word for it, i try to do research because I want "a bit" more flush. Online says a RANGE of different things, so i call a few places to confirm and THEY all have different specs. One wheel and tire place says i need to go et 35. One says 30. One is 32. One place told me 25. A wheel manufacturer that are all made to order recommended a 15 or something crazy. A guy online shows pics saying he's running 20 and lowered. Everyone i question tells me to go measure. So, I follow everyone's advice and go measure fender clearance using a string and weight and measuring to my wheel lip and the outmost point of my tire. Im getting approximately 5/8ths of an inch, OR 15.875mm.

I go on "willtheyfit.com" and play with sizing. It says my stock "poke" is 75mm; so an 8 inch wheel with et20 will gain 7mm, 9 inch wide and et30 I'll gain 9, 9.5" will get me 11mm at 86mm "poke".

So ok, i convinced myself a 9.5 with 35 was the best option, if I want more, I can add spacers; which I'd rather not do if I csn get it done right, but im not wheel offset genius.

I call to order one of 2 wheel options, give the guy the specs, tell him ive been so confused and why. He says, "ill call the manufacturers and see what they say". One wheel manufacturer has no bmw data and doesn't think they will clear brakes. Awesome, thanks for not trying to sell me broken dreams im stuck unable to use. The 2nd wheel manufacturer says, oh yeah, we have not only the data, we have our own m240, and we run 19x9.5 with a et22 AND a 2mm spacer! So that's what's recommended to me. Im perplexed here.

Without the spacer on that spec wheel, will it fit says im gaining 15/16ths... almost a full inch of "poke". Where the he'll do i have an inch of room!? I didn't place the order. I asked what happens if they are wrong and they dont fit and I got "i dunno, we've never had that problem before"... that wasn't the most reassuring answer I wanted. I dont want to pay for and sit on wheels no one can use.

Unless im misunderstanding "poke", or someone here with experience can back it up, or give me real personally used specs, im super hesitant to buy any wheels now. Im hoping im just psyching myself out...

Anyone? Thanks in advance

Im sure its been done to death, but "perfect" aftermarket wheel offset??

Story below, but in short, what's the best wheel spec for a 19x8.5 or 19x9 wheel with factory 225/40 all season runflats?? I want to bolt on and be as flush as possible.

​

​

​

Long story: I went to buy some wheels. I did what I thought was extensive research only for the wheel company "specialist" to tell me the specs I wanted were too "aggressive" amd wouldn't fit, and then he told me my specs were wrong...

​

I have a 2026 g42 m240i xdrive with the 995m wheels with all season runflats. Just looking to buy a new set of wheels, i HATE these oem wheels, and keep the existing tires (for now, with a possible SLIGHT width increase further down the road). So i have the stock wheels being 19x8 with an offset of 27, with 225/40/19 tires, square setup. Looking to go 19x8.5 or even 19x9 with a 25 or even 20et.

​

The sales guy told me I'm crazy. Stock et is 40 on his side, according to his computer. I tried telling him that I could be wrong, but an et of 40 would be in the rear if I had a staggered setup. Square 19x8 have the et27. He told me im wrong.

​

You can tell me who's right or wrong, ultimately I don't much care, I just want a flush set of new square wheels that both allow my oem tires. What size(s) would you recommend?

Ordering a concave wheel?

So I'm not one to order a set of custom wheels where I input the desired et and whatnot, so i truly dont know whst specs to change and what they should be; ive always just told a company the size diameter wheel I want, and basically take what I'm given. I recently acquired a 26' BMW m240i x-drive with stock bicolor 995 wheels running 225/40/19 all season runflats. I'd prefer to stick with a 19" wheel and just reuse my current stock tires, although at some point I'll upgrade those at well. I BELIEVE my current wheels are both 8" wide because i don't have the staggered summer setup from the factory; otherwise the front would be an 8, rear would be 8.5.

My real question is, if im looking at concave wheels, and ive read that the "perfect" spec for a flush to fender wheel is, for example (and im making up numbers here), 19x9 with a et27... do those numbers change of it were ordering a concave wheel, or do I give those specs to the manufacturer? Thanks in advance, pic for attention

Add your 3d files here...

I apologize if this has already been done, however I did a search and didn't get any results. If its been done, please remove. I figured I'd start a thread where we can post shareable 3d print files for our cars... from body parts to engine mods to regular scale models and bmw keychains. As soon as I get back to my shop computer in a few days I'll add mine. Meanwhile, if you have some you feel like sharing, please post.
