I just bought a 1990 560 SEL that has different wheels on it, (see below). The seller claimed they are original Mercedes wheels from a later model but I can't seem to figure out which one. Can anyone help me indenty them?

2003-2005 W211 E320 wheels

Thanks! I don't suppose you'd know if the offset is OK for my W126?

bolomiester, look at the back of a wheel for the designation "ET" followed by a number which is the offset in mm. The MB Star logo on the back of the wheel indicates a genuine MB wheel.

The offset as well as the size and MB part number should be on the back of the wheel usually on one or more of the spokes.

Early W211 E320 wheels. 2003/2004 era.
Don't remember the size off top of head, but most likely they are 16", 17" MAX.

They made both a 16" and a 17", the 17 was put on a 500 sport edition IIRC and only for a year or two and it's fairly rare. The 16 was the base wheel for several years of the 211.

OP, the real key is not the offset (if it were wrong, you'd know because it would be rubbing) but the lug bolt.

Your chassis uses the 12M bolts with a 12R ball seat, and those wheels were designed for a 14M bolt with the 14R ball seat. Often people just mount them with a shorter bolt (the facing is much thinner on the modern wheels) which is unsafe.

If they have the wrong bolts, you can order the correct ones from otisinla.com, you'd need R14x12Mx1.5x26mm IIRC.

Good luck.
