I was wondering if this size 20 inch wheel will fit ok on my 428i M sport lowered on H&R supersport.

Front: 20×8.5 30 offset
Rear: 20×10 38 offset

If these will fit without rubbing issues what tire size is recommended that's not too aggressive?

Thanks in advance.

You probably want as thin of a tire as possible. Definitely 30 series front and 30 or 25 series rear.

I think 20" are to big. The 19" should be just fine if you are lowering your car. Doing 20's w/ lowering would mean you may have to change your suspension set ups. (which I dont know to much about) lol I had 20's on my E90, then with all of the rubbing and flats. I had a flat every 2 to 3 months. I'll never put 20's on a Bimmer again.

That should fit fine. I am running 20x9 with 35 and 20x10.5 with a 45 and rear still has a bit of room. Just depends how low you are going to determine tire size as you can run a 30 series or 25 in the rear.

That's what everyone told me when I said I wanted 20's. I got them and had zero issues rubbing or flats or bent wheels. I don't doubt you had issues because i had similar problems with my 18s back in the day which made me more nervous and thought well if I had those problems with 18s most likely 20s will be too. Took the risk and glad I did. The 20s on the F30 for me make the car and zero problems is an added bonus.

Not definitive since we haven't mounted wheels on a 4-series quite yet.. but if fitment is anything the like previous gen 245/30/20 285/25/20 should work.

Whatever fits an F30 will fit an F32. As you can safely assume they have the exact same wheel well profiles.

Don't expect e92 3 coupe wheels to fit though. The offsets are way less aggressive and the wheel well is overall smaller compared to last gen.

20" on the F30 looks right. That's what I went with. 19's were the rule on the E92 but I think 20's should be on the F30/32

20s look great on a 4 series. I have done a few 20 inch setups on the 4 series and I love them. Run a 245/35/20 and a 275/30/20. What wheels are you looking at?

Fitment is on Point with H&R Sport Springs and 20" Wheels. Take a look at the setup on this white 435i.
