Not seeing a lot of mention of wheel offsets here. Keep in mind not all wheels will have the same offset. To properly measure spacers you want to take into account both wheel width and offset.

I have a ‘24 on order with the 791m staggered wheels:
Front 19x8 ET27
Rear 19x8.5 ET40

I’m thinking about trying 10mm all around. Will report back when the car arrives!

Well no one is mentioning offset because most of us have stock wheels such as the 791M wheel, which means we all share the same offset.

Love the dual tone wheels. Wonder if you could share the code, for the wheel I mean. Beautiful.

I’m not sure their exact code, but they’re 792m wheels. They were my stocks, I’d say I’ll sell them to you, but your in Canada. Thank you for the compliment though.

Fair point but some people have factory square setup, others have factory staggered setup which has a different width & offset in the rear. Just saying it’s important to take that into account when comparing one person’s spacer sizing to another’s.

What size spacers would you recommend?

19" wheels with a staggered stance, 9.5 width in the rear and 8.5 in the front.

Lowered with H&R springs.

What do you think of 12mm all around? Any ideas welcome

Hard telling from the pics. Looks like the rear has considerably more room than the fronts but maybe its just the pic angles. Maybe 12mm front and 15mm on the rear?

I'll consider that. Thanks!

The fronts stock are tucked way in there compared to the rear, although the rear offset is much higher also.

I have a square setup 245/35/19 all around. Need help with what size spacers to get. Was previously running 225/40/19 square with 15mm spacer all around and was perfect. But since I switched to wider tires I’m not sure if I should go smaller spacers? Any ideas or advice would be appreciated! I was thinking maybe 12.5 all around? Don’t wanna spend money on spacers then have to return them!

Here's the situation before spacers for more context:

Rear wheels (9.5")




Front wheels (8.5")

I am not in the majority here but I went 12mm front and 10mm rear. Wasn’t looking for too aggressive more oem+. The fronts are tucked more than rears from my perspective. I tried 10 front and 12 rear but it looked offset. 3mm gap from tire to fender both front and rear.

And staggerd set - 8” f w/ 8.5” r

Looks very good!

I currently have the stock 19" 792M rims on my M340 with the stock Pirelli 225/40/19 tires with 15mm spacers all around, and I agree, it looks perfect!

If you are keeping the same rims and just upgrading to the wider 245/35/19 tires, you shouldn't need any spacers to achieve the same look as your prior set-up. The reason I say this is the 245 tires are .7 inches wider than the 225 tires. A 15mm spacer is .59 inches wide. So you are still wider by .11 inches with the 245 tires and no spacers. Again, this scenario is assuming you are keeping the same rims and just going with the wider 245 tires.

My advice is to install them first without the spacers and see how it looks. You can always add them later. Now if your are changing rims, that's another story due to the offsets.

They are more flush that I thought. The TBH I think you may want to just try different size spacers out. Starting with maybe 10 and going up to 15. I think 15 might be too wide. But I think you just need to feel it out.

Thanks for the tips man. Will do!

Hey bro thanks for the response! I'm posting this after already installing the wider tires. It's weird because it I was thinking the same that it should look even wider than before since 245 is 20mm wider than 225 tires. But even with the wider tires the wheels looked tucked in without spacers. After measuring it seems like 10-12mm spacers will give me the look I need. But yeah super weird how even with wider tires I still need spacers to achieve the look I had with 225s. Idk if I'm tripping but I'll just pull the trigger on some 10 or 12mm square spacers and try.

This is 235/40/19 on 791M wheels with 12mm front and 15mm rear spacers.

Nice! 😍👌🏻 What do you think about the spacer size for 19x8,5F(ET25) and 19x9.5R(ET35)? 255/35 tires all around. Would 10mm front and 12mm back be overkill? Worried about the ET25 for the front. Maybe 5mm front and 10mm back?

[Bumpinjeep]

Hey gang, might as well ask. I have a buddy with a 23 m340 x-drive. I have a set of 15mm and 12mm future classic spacers off of my G87 from when I ran my stock wheels. Have any of you guys used different width spacers on a AWD car?

[Yotempole]

Hi all, so I am about to grab a square set of wheels for my winter tires at 32mm offset. the wheels are 18x8" ET28 ASA GT14s. Tire size: 235/45/18. Seems like the front wheel in particular is going to be quite far in. Any ideas of a good spacer set for these wheels?

Also if anyone knows the offsets of the staggered 19" 791M OEM wheels I can probably interpolate from the posts here.

[Yotempole]

Okay so after studying the thread it seems like the fitment I want on my wheels is the same as crpediem_2's. He used 12mm in the front and 10mm in the back to achieve his fitment.

I've calculated the distance from the wheel mount to the outside edge of those wheels using his offsets to determine (in my opinion) perfect fitment. It seems like for the front, the ideal distance is 88.6mm, and the rears are 77.96mm on a RWD 330i.

For the ASA GT14 wheels with a 32mm offset, it looks like they will be 8mm further in than stock on the front, and the same as stock on the rear.

I've decided to buy 13mm, and 10mm spacers for the car. During the winter I will use the 13mm in the front to bring the wheel back to stock (and a little bit further, but not to that perfect distance), but will skip on the rear so that it doesn't look too unbalanced.

In the summer I will keep the 13 in the front and add the 10 in the rear to achieve perfect fitment on my summer 19" wheels.
