Square set-up (F30 340i): 19 x 8.5 et30 ~ yes? no?

damascus · 11-10-2019, 07:54 AM

I'm looking at a square set-up for my 2016 340i (RWD M-sport). I drive at least 120 miles daily (all highway) and want to rotate my tires.

Would these work on all 4-corners?

Wheels: 19 X 8.5 et30
Tires: 255/35/19

Thanks!

Sounds likely. A typical square setup would be 18X8 et34 (stock 416 wheels) with 245/40 tires. This is what I run. Yours would move the wheel 10.35mm outboard and 2.35mm inboard. That should put the tire in about the same place inboard so that it shouldn't rub. I would think less than a half inch outboard would still work.

Edit: would also depend on type of tire (my Michelin 245/40's are a lot wider than my Pirelli 245/40's) and camber. Right now my setup with the Michelin 245/40 and around -1 degree camber is pretty close to dead on flush at the top of the tire in front (sticks out from bumper slightly at middle and bottom of tire) but looks to have a bit more room in the rear.

I have that exact fitment on my F31, Vorsteiner VFF105 in 19x8.5 et 30 running BBK as well if of interest to you and everything is perfectly fine for fitment.

My tires are a little different, I wanted a bit more sidewall for the roads by me, fill up the wheel well some, and also a bit of stretch but nothing crazy. Went 225/45/19 and they look awesome.

I like the 9.5 et35 square spec myself (with 255's). The front tire is very close to the strut so you need to confirm there's enough clearance - success depends on tire.
