Here's a photo of a set of 400m "take-offs" I just bought
from a dood with a new 340i .. with summer run flats.

The old 393s are in the back seat.

Here is my 340 xdrive with BMW 441m wheels in ferric gray. They are similar to the 400m wheels my car came with but the center and spokes have a more aggressive look. I have a square setup and no suspension mods.

Looking good guys

Can anyone with aftermarket 18" wheels chime in here please. I'm ordering a set of 18x8.5" VMR V710s. I was told that I should go with 225/45/18's or 235/40/18's. However the tire place is saying that I should go with 235/45/18 tires. My car is a RWD 328i lowered with Dinan springs. What are you guys running? Would 235/45's rub with such a mild lower (3/4" front and back)?

18x18.5" is extremely wide. Are you planning to drag race your 328i Modern Line..

JK. 18x8.5 is the same as a stock 400m rear, so 255/40 is typical. I don't think 235/45 would rub, but the sidewall is taller than stock. 225 is a bit narrow for 8.5 inches, so I'd wonder if they offer 18x8, and get 18x8 fronts and 18x8.5 rears, so you can run a typical 225/45 and 255/40 staggered setup. Otherwise 235/45 all the way around should be fine if you don't want staggered. Don't think I'd choose 235/40 all the way around.

with dinan drop, 8.5" wide and assuming +35 offset, 235/45/18 will fit no rub. personally i'd go 245/40/18 on 8.5"

245/40/18s would look more mushroomy wouldn't it?

245 is optimum fit on 8.5, straight sidewall. 235 is slight stretch. 255 is slight mushroom...

+1 on 245.

Also 245 will be closer to OEM rolling diameter than 235. If you are leasing or care about resale value, a -2.2% rolling diameter = 2.2% more mileage reported on the odometer for every actual mile driven.

To get exact rolling diameter 255/40R18 is also a choice, but imo they are too heavy and fat for a 8.5 rim. http://www.tyresizecalculator.com/ch...rim-size-chart. 245 remains the best balance.

245/40 or 245/45?

245/40. here is a great tool for checking the fit of new wheels/tires:

I recommend 245/45!

Fills the wheel gaps, protects the wheels and corrects the optimistic speedo.

Oddly using the same size tire I am running stock with 8" wheels, the difference with 8.5" seems negligible right?

Yes the fit is the same, only difference is that the tires will be stretched
