E39 (1997 - 2003)
The BMW 5-Series (E39 chassis) was introduced in the United States as a 1997 model year car and lasted until the 2004 when the E60 chassis was released. The United States saw several variations including the 525i, 528i, 530i and 540i. -- View the E39 Wiki

Wheel Spacer

Can anyone knows how thickness of wheel spacer needed for 2003 525 if these are compatible. The rear wheel rim size is 9JX18EH2 with tire size of 275/35ZR18 and the front wheel rim is 8JX18EH2 with tire size of 245/40R18. They said these rims and tires came off from 5 series. The rim and tire with the car right now is 8J17H2 (235/45R17). I appreciate for all input. Thank you.

You need more info. Are you taking about an OEM BMW wheel? Or aftermarket. And if it is and aftermarket wheel, you need to know the offset. You also need to know if it came off an E39 5 series or not. If they are off ANY OTHER 5 series than an E39 you will either need to have the wheels hub bored out, or buy adaptors.

These are OEM from 5 series but I am not sure what year. Could you tell the rim offset by the rim number I mentioned above?

You need to find out the center bore and offset. Posting a picture will help with identifying the wheels also.

No wheel spacer required. If you meant to say "what is the centre bore" for a 5 series BMW it is 74.1mm.

After market rims with smaller bores will need to be bored out to 74.1mm, wheels with larger bores are useless unless you can find reducing hub centric spacers with a 74.1mm centre.

Putting on spacers means you're adding width and if you're trying to put a 275 tyre on a 525...forget it, by the time you add a 10mm spacer youre already at 285 wide, not only will you fender rub, you'll destroy your rear quarter panel.

The only information you've supplied as to the 18" wheels and tires is that the front wheel is 8"x18" and the rear wheel is 9"x18"...none of the other alpha/numeric characters you gave us mean a thing.

Also, it does matter as to which model year "5 series"...there are multiple generation 5 series and their wheel's hubs are different (at least the 39's wheel hub is different)...so MODEL YEAR of the 5 series is VERY IMPORTANT information to divulge.

As far as the width & height of the 18" wheels...and the 18" tire sizes...that's not an issue because it is the size of the 18" wheel/tire combo for the e39 M5 and is compatible with the 18" wheel/tire combo of the 2003 540i M-sport pkg...thus is compatible with other e39 sedans if these are original BMW e39 5 series 18" wheels.

If the wheels are from an e12/e28/e34/e60/e61/f07/f10/f11...then NO...the wheel hubs will be too small (72.56mm instead of 74.1mm).

See the BMW wheel size chart below to compare specs to see how compatible they are:

Thank you. By the way, could these numbers have a meaning to decipher the offset, etc. of the rim?

5th picture shows the wheel size and offset. 18x8 and +20 offset. These are not E39 stock wheels so the center bore will prevent them from being a direct fit. You can bore out the centers to 74.1 or get spacer adapters. eBay has cheap ones that work and have a 74.1 bore for the hub and 72.56 bore for the wheels. The minimum width spacer adapters you can use is 12mm I believe. Do a search for spacer adapters for the E39 on google

Thanks Eparayno. So the IS20 means the offset. The seller lied on me because he said came off from 5 series.

It's probably from a newer 5 series but definitely not from an E39

He didn't lie, he just misguided you...they're standard 5 series E60 rims

Ditto statement above...he didn't actually lie...but he was disingenuous by not disclosing "which" 5 series the wheels came off of. As you can see in the BMW wheel chart above...not all 5 series wheels are compatible with all the OTHER generations of 5 series BMWs. The wheels you're looking at (as already mentioned) come off of an e60 5 series.

HINT: BMW wheel offsets can be identified by two different ways. The offset will proceed either "IS" or ET". For example, both methods below can be found describing BMW wheel offsets...the "20" would equal 20mm in the below examples...but other numbers could proceed the alpha characters & they would represent the offset in millimeters:
  • IS20
  • ET20

All of the "e" models (generations) below are "5 series models"...model year is important to know if you don't know the specific "e' class...because model year will lead you to the specific "e" class (aka generation) of 5 series BMW that is being considered:
  • e12
  • e28
  • e34
  • e39
  • e60
  • e61
  • f07
  • f10
  • f11

BTW, when BMW owners don't identify their model year or "e" series...once that model's nomenclature goes into the 2nd, 3rd, 4th, 5th, etc generation...than it's a turkey shoot as to what 1,2,3,4,5,6,7,X series that is being referred to.

An X5 could be anything from a 2000 model to a 2016 model and could be 1 of 3 generations (e53/e70/f15). Same goes for a 5 series ("e" class has already been listed above) and can be anything from something from the 1970s up to 2016 model year...as well as a 3 series. Without the model year or "e' class...its rather vague as to what BMW model one may have or be asking or talking about.

Hello Gents, recently bought an 18" staggered wheel style 71 with offset of 47 F and 50 R,
just realized that it will not fit my e39 with 74mm center bore and it is pushed too backward that it touches the brakes and shocks, to make the long story short, i went to my local shop for wheel spacers measurement, turned out that i need around 40 - 45 mm wheel spacers to correct the offset

here's my dilemma:

will i buy and install the 40 - 45 mm wheel spacers, is it safe? does it even exist?
or will i just simply sell the wheel style 71 and just another one with the correct offset

thanks in advance Gents! btw, newbie here
