Hey guys. I have an 11 LCI e90 sedan, 335d if it matters, taht I bought a set of oem style 437m wheels for. I am wondering what the largest size tires would be for a sport suspension that doesn have any fitment issues or rubbing. Basically I dont want to bacon the fenders and dont want to rip wheel liners out. But I need all the tire I can get for this amount of torque. Any help would be appreciated. Thanks in advance.

I saw only one post that had someone run a 235/35/19 front and 275/30/19 rear but he said he thought a 245 would work. Basically since these have been around a bunch I am hoping someone can give me the info without trial and error on my part.

Can you type in the 437m wheel specs? Makes it easier to understand. I also drive a 2011 335D. I'm doing a wheel/tire change as well but staying 18" diameter. I'm attempting 255/35/18 in front but you've got to have right ET on wheel to attempt this.

Sure. The 437m specs are 19x9 et 29 front and 19x10 et 40 rear.

From the two posts I was able to find across the inter webs the rear size is pretty consistent as 275/30/19. The fronts are the only ones that see mto be variable and not concrete. I realize there are some size differences between manufacturers to throw into the equation as well. But The factory m4 size of 255/35/19 was reported to rub. Someone else ran 235/35/19 without issue. Both said 235-245/35 would probably work but nothing definitive. I do not want rubbing so I am ok with whatever size is the largest I can go without issue. 245 /35 o if I can maybe 255/30 instead of 35???? I just cant imagine this not being settled already as to what can be ran as the two threads I found were several years old.

19x10 et40 with 275/30/19 is fine, I'm running the same size rear (et38 though) and don't rub
I recall hearing that 19x9 with 255/35/19 will work, one thing I would be a bit worried about though is at full lock if the tire contacts the inner fender. I know the 245/35 front works as I have read it on here.

Thanks for the reply. Yeah the rear I am not much concerned with fitment wise as it seems to be pretty unanimous it works fine. For the fronts though the 255 I have read rubs in various conditions. I guess I was hoping someone would tell me a 245 is for sure no issue. As I know a 235 will work but Id like to get a little bigger if I can.

I think with a 19x9 et29 you will be fine with a 245 tire. I plan to run a 255 on my 19x9.5 et32 when the tires on wear out and don't expect any issue.
