Hey guys! New owner here of a 2016 328D. First Euro in a while. Last one i did nothing with. This one I am interested in putting wheels on. I'd like to preface this post with i've been looking all over for wheel types, offsets, whether I want squared or staggered and stances. A lot of info to take in. I found Apex's guide that they put together. I've really been digging this look:

In my research, everyone says that +20 is too aggressive.
I have already ordered the H&R supersport springs. What I was wondering if I should stick with safe: Front: 19x8.5" ET35 with 235/40-19 tires
Rear: 19x9.5" ET43 with 265/35-19 tires
I just want to make sure I get it right before I spend the money. I dont want any rub or anything that will damage the car. About 15 years ago I used to bag cars so tearing apart the suspension doesn't bother me. The biggest bother is getting these freaking wheels right. LOL. The hardest thing I had to deal with was clearance for 24's back then. If there is anyone that could help me with pictures of something similar and give some info and insight, it would be greatly appreciated. The guy that I posted above ended up selling his car and hasnt been on site since 2015 or else id reach out to him. Thank you in advance.

I would run 245 front and 275 rears. It'll fit the wheels better and fill up the fenders a lot better.

with a 245/275 setup on a 19 you end up shorter in tire diameter because you cannot run 40/35 series tires. Id stick with 235/265 in the PS4S on those rim sizes.

If you want as flush as possible look to an et of 40 out back. Could push it to 35 if lowering as well.

Thanks for the info. Any pictures? Are you lowered?

I have the H&R super sport springs on the way. Running with et35, when you say push it, is there a chance of rub? I want it flush as possible with no chance of rubbing problems. Thanks for your help.

The aspect ratio is just that, a ratio. So with a wider tire you run a smaller aspect ratio to keep the sizes closer. Or you could run the same aspect ratio, but then it'll be taller on a wider tire.

I went from 225/45 and 255/40 to 245/40 and 275/35 and the difference in diameters isn't noticeable.

Yep, this is my car with 245 tire et30 front and 275 tire et40 rear. Yours would have more room on both ends since the offsets are higher.







And this was before with the stock wheels (same ride height). Even though my new setup was slightly smaller diameter than stock (like 1/4" shorter") it looks pretty similar and the wider tires helped it fill up the wheel wells much better. And with 245/275 you can still easily keep the front and rear diameters the same.

kern417 Yes but those tire sizes are 26.72" tall and are more inline with the F10. The F30 is 26" while the 235/40 i proposed is at 26.3.

Soooo get a smaller tire lol. If you have 19s then get a 245/35 and 275/30. Simple.

The only way to keep them the same as stock is 1. run stock tire sizing or 2. go up to 255/285, which is hard to fit without perfect offsets. otherwise it will always be slightly taller/shorter.
