Will these tires / rims work on 2003 E39?

Hi,
I am somewhat new to the group, and the car is new to me as of a few months ago.
Needs to get some snows on it asap.
I did some research on the site but I am lacking some basic tire / wheel knowledge i think.

I was wondering if these would work on my 2003 540i m-sport.
~4 Blizzak Snow Tires Size 245/50 R 18 on BMW Rims. Rim size ET20 from 2006 750i~

Currently has 235/40 R18 front and 265/35 R18 rear. This new setup would obviously not be staggered as it currently is. I guess the issue is, are the new tires going to be too high, and maybe too wide in the front? The owners manual did not give any specifics.

Any info from the group would be greatly appreciated!

If the wheels are from a 7 series, the hub might not fit.

245/50/18 have the aspect ratio too big, and the speedometer will be off (as well as the calculated distance).

Thanks doru. Much appreciated.
I could deal with the sped. and distance being, off but the hub size would be an issue.

Yes it would. Yours is 74.1 mm, the 750i one is 72.5 mm. If it were the other way around, you may get by with hubcentric rings, but it's not gonna happen here.

They will not, E39 hub is bigger and tires are too tall in any case.

You would probably be better off with a 235/45-R17 or 225/55-R16 with E39 specific wheels. either option will clear your factory brake setup. The tire cost will be reduced from any 18" configuration. Look in this forum's classified section and or Roundel magazine. You will find quite a few options besides buying new from tire dealers.

Got vredestein xtreme winter contact in the 235 40 18 and 265 35 18 setup.. really good tires from what I can tell.. however they take about 100 miles to break in properly.

If you look at the tire pressure label on your driver's door jamb (or the owners manual)...you should see a list of BMW recommended tire sizes...including winter tires. Also, take into account the overall circumference/diameter of the recommended tire sizes for the e39 versus tires from another BMW model. You need to stay within 3% (+/-) the overall diameter/circumference...regardless of upsizing or downsizing the wheel size. You can google for a tire size calculator...then input the original tire size...to see how far off another tire size is.

For example...the image below was from the label on the door jamb of my 1999 540iT...you can see there's a list of winter size tires:



(the image below is from an earlier model year e39 owners manual)



And the chart below shows the difference between the BMW wheels:
