Hi there,

Here is an example of a stock F31 on 19x9" ET30 SM-10 wheels wrapped in 245/35-19 Michelin PS4S tires:







With stock X-drive ride height, as you can see, this setup does poke slightly. However, there was no rubbing under suspension compression with these wheels and tires on a stock F3X. With lowering springs or a slight drop in ride height, typically most of the "poke" with this setup goes away.

If you have any other questions, please let me know!

I'm running the exact same setup but lowered on Bilstein B14s. Fitment is pretty much perfectly flush with no rubbing at all.

I can deal with a slight poke, no biggie. I'm on RWD and I wonder if I pack a little more meat on the front tire from 35 to 40, will it cause rubs? I should also mention that the wheels are square 8.5 around.
Thanks for the feedback greatly helped!!

Im running 255/35/19 et +35 on 9.5 wide square no rub. 9.5 wide +35 is the max you can run up front stock anything bigger it contacts the strut. So at 8.5 wide you should be good.

245/35 tires and I'm RWD. It's a square set though so should be fine with xdrive.

I'm curious why you went with 245/35? Apex has said 245/40 fit with no problems and are closer in diameter to OEM.

I just went with what the Apex staff pick was. Didn't want to have to roll my fenders if I go lower and they are the same rolling diameter as my stock set.

Do you think running an aggressive fitment such as ET30 will have long term negative impacts on suspension and the rest of the car?

Gas mileage will probably be a little less since the tires are wider, nothing really noticeable though. If lowered on coilovers you'd probably need shortened swaybar endlinks to prevent preload on the front swaybar. I don't have any yet, but they're next on the list. Other than that there should be no issues at all.

Makes sense. I'm not lowered just trying to find out if it's worth running these wheels or selling them

Where did you find the info that this is the max you can run up front on stock suspension?

I know from personal experience picture below of the inside of my front wheel and strut distance on stock m sport suspension. The only way to run higher offsets beyond +35 on a 9.5 wide rim is to run spacers.

Do you know the maximum tire width on a +35 for rear? Im looking to do a 245/35/19 front and 275/30/19 rear on Aodhan AFF7 staggered (8.5 and 9.5) both +35.

Ive seen guys run 19 x 10 ET 40 w/ 275/35 in the rear successfully but they are on coilovers. you may want to wander over to this thread https://f30.bimmerpost.com/forums/sh...1166496&page=9 give you some better options. Also you want to keep the rolling diameter less than 1% on your tires right now you are at 1.2 % with those two tire suggestions so that could potentially lead to transfer case issues if nobody has told you about this yet.

et30ish... ;)

Here's mine - 19x8.5 et35 with 255/35/19 square. However, i'm running 5mm spacers in the front and 12.5mm spacers in the rear. So effective offsets are Front 19x8.5 et 30 | Rear 19x8.5 et 22.5. Lowered on Eibach Pro Kit

Circling back to this to clarify to my original question. Based on your input I should be able to run 40 side wall on the front with 235r19 and ET of 30?
