Do any of you have pictures of your 5-series on 408M wheels? I know many of you use them for winter wheels, but I rarely see pics of them installed.

Link to a f11 on the 408m. Very nice OEM 19" wheel I think.

Nice, thanks. That's what I was looking for.

My winter setup, 245/45-19, 1" larger diameter than stock.

Car is lowered a little over 1" on coilovers, using 10mm spacers up front as I have negative camber arms installed.

That looks really clean!

This is perfect, my car is the same color. Love that stance.

What size tire are you running?

Are these forged?

Sorry I missed it, thanks for replying.

Don't think they're forged, but the are on the lighter side being a 19" OEM wheel.

Thanks! Yeah cause I actually like the 351 and 373s. But they are all known to bend super easily. Running 343s right now but 20s can be harsh on roads

408m front and rear wheels are completely unique as well. F/R offset is 32/25mm, and the rears actually have 7mm more concavity than the fronts. A small detail I had to measure to confirm, it's not obvious just looking at the wheels.

I guess when BMW charges that much for accessory winter wheels they can justify double the tooling cost, part numbers, inventory logistics etc. lol

The light weight was one of the reasons I wanted these. They are very light for an OEM 19x9 wheel. Also needed to offset the added weight of my cosmetic brake upgrade.

With the taller 245/45 tire I have WAY less pothole anxiety.

Can you tell me more about how you chose spacers? I bought a set of 408 rims (32 offset, square setup for xdrive) and put the rim by itself on the front hub and it’s nearly rubbing on the front suspension, even without a tire. Is that why you used 10mm spacers on the front? Any spacers on the rear? I’m thinking of mounting 255/40-19 tires on them.

Agree that it was strange they bothered with the different offets for the winter option for summer wheels that are 9" 32mm and 10"34mm front and rear.

What is stranger to me is that they bothered with that, but then put in the same spec for the F13 M6 which has 9.5" 31mm and 10.5" 19mm wheels.


There are other subtle changes BMW makes, ie 17x8" and 18x8" F10/11 wheels are 30mm offset, then 19x8" and 20x8" are 33mm.

Also for F01 up to 19" the rears are 9.5" 39mm, then 20" or 21" are 10" and 41mm.


I'd really like to be a fly on the wall in those meetings! My first question would be why is the F10/11 rear so sunken when compared to the front

Did you buy the wheels new and get 4x fronts? If not you probably have 2x fronts @ 32mm and 2x rears at 25mm.

I used 10mm spacers as they are the narrowest regular spacers available for the F10. If you go less than 10mm you need to either use hub extenders or use a spacer so small that it's barely worthwhile.

Ideally I would use a smaller spacer as my setup on the front will rub with high compression and too much steering angle, like going into my driveway over the 3" tall curb the city so brilliantly designed in front of our house. Without the spacer I have no clearance issues, but the rear 25mm fitment is pretty aggressive looking and the front looks out of place by comparison. If I had standard (more) rear camber and didn't use negative camber arms up front the fitment would likely be just fine without the spacers.

If you have a truly square setup you'll likely be fine. The only way to know for sure is to try it. A 255/40 is shorter and wider than what I'm using and my camber/lowering situation is different, so we're not really looking at the same situation. I hope that helps… probably not much!

EDIT: Regarding clearance to the front suspension, people use the 343m M5 wheels on the front with 255's and have no clearance issues as far as I know, and that's 2mm closer to the suspension (20x9 with 34mm offset). You should be ok.

I don't remember having clearance issues when trying the rear 408m on the front (25mm offset), but I'd want to try again to be absolutely certain. EDIT #2, LOL, the rears are 25mm offset, 7mm less, so they will have 7mm more clearance to the suspension. It's early and my brain isn't quite working yet!

It's strange to me as well, especially when their efforts result in a fitment that's still not great... far too conservative in my opinion, more so even than the stock summer wheel/tire package. They should have had a third 408m option just for the rear of the F13, another 7mm decrease for a 19x9 ET18. The 408m looks lost in the vast wheel arches on the back of that car.

BMW does do strange things with wheel offsets, for sure. If you consider the lengths they went to on the F10 to make clearance for the rear wheels (huge wheel arches with rolled seamless fenders) they probably could have done much better on the rear fitments. The front fitments are pretty decent from the factory for the most part.

I'm pretty sure they have a rulebook to follow for clearances that has some strange guidelines. A rulebook that needs some revisions.

My car came with the 434m wheels and they're even stranger; 20x8.5 ET33 front, and 20x9 ET44 rear! The front looks really good but the rear looks terrible, needing a 10mm spacer just to look acceptable. Here's my car stock, a pic from the sale listing:

I know a guy in the UK a long time ago running 409m (he had CCBs, the spec is identical other than the rim being 20") and he was running a 20mm spacer. He wasn't running chains though, just winter tyres and that is a big thing to consider.


For F10 M5's, one thing that a lot of people don't realise is that the rear axle and brakes are completely different for the M cars. From hub face to hub face on a non-M the distance is 1687mm. On an M car it is 1650mm.

Hence why on a non-M 5 series the 343m wheels fit so much better and look more aggressive.

Assuming 275mm wide tyres on the stock 44mm offset wheels, the top corner of the tyres will be 1874mm apart. On an M5 with 34mm offset wheels and 295mm tyres the measurement is basically the same at 1877mm.

On a non-M with 285mm wide tyres on 343m 34mm wheels the measurement is 1904mm and with 295mm tyres it is 1914mm. I know some have said 295mm rub and as such 285 is also a common rear size people run.


I completely agree with you that the stock front setup is actually pretty good but the rear is very weak. Hence my thread I made a little while ago in here looking at E65 wheels which are 24mm offset for both front and rear and E90 M3 wheels which are 29mm front and 23mm rear.

The front would be 1mm for the E90 M3 wheels or 6mm on the E65 wheels further out with 245mm wide tyres or 1mm further out with 235mm wide tyres with the E65 wheels, so very close to stock.

The rear is more aggressive though and is quite close to what people run with spacers with either 265 or 275mm tyres or of course 343m wheels. I really do think that for an OEM+ setup the 408m or 409m are a great option, but E65 or E90 M3 wheels are also a very good choice. E65 wheels are heavy though!

E65 wheels with 275mm tyres is the same outer edge tyre position as 343m on 295mm and E90 M3 wheels are another 2mm out which is starting to get a bit aggressive so perhaps 265 might be a good option - I think thats what I'll run with the E90 M3 wheels on my F11.

343m wheels on F10 often rub even with 275s, requiring additional negative camber. I'm not sure if they're rubbing the steel fender or the composite liner, but several reputable members here have had the issue.

Hmm, I thought I'd seen the good majority with 343m running 285 tires - no chance you're talking about M6 wheels with a 19mm offset instead of the F10 M5 34mm?
