I know that factory alloy wheels from an W124 E-Class don't fit properly on a W126 series (too much offset, I believe), but are the S-Class wheels an OK fitment for a W124? I know the bolt patterns are both 5 X 112.

Specificly, 4 wheels off a '91 420SEL on a '91 300TE

Thanks, and CHEERS!

I fully expect that the offset will be wrong. Somewhere on the inside of your wheels you will find a designator that starts with ET, like ET35. This is the offset. If the offset is the same then you're good to go.

I agree...but the early 86-88 W124's had the stamping ET49. In the 89 and later years, the part number changed. I don't know if the offset changed. Maybe not.

Part No. W124 rim 1988

"If the offset on the E-Class wheels doesn't fit on the S-Class because of interference with calipers, suspension, etc. it w/b because it moves the centerline of the wheel/tire combo too far inward. Alternatively the S-Class wheel would then move the centerline outward on the E-Class hub, and...

if not TOO much farther outward the result would be like having a spacer between the wheel & hub..."

If there is any binding or rubbing on fenders or frame it wouldn't work, but he seemed to think +10mm (or 1/2 inch) shouldn't cause any problem.
Cheers!

p.s. I do know that "MB does not approve of the use of spacers", but I'm told the reason is the addition of another variable in the mounting surfaces (another layer in the wheel/hub sandwitch), not that it changes the offset.

W126 wheels don't fly on a W124. Penetration of rear (vs. face) of wheel too great. No spacers.

W124 wheels "fit" on a W126 but stick out the additional 17MM of the offset difference, 40 vs. 23, and kind'a have a "gang'sta" look, IMHO.

Well, I tried...

Thanks to all who read and responded.

Cheers!

I just put 1989 w126 wheels with 205/65/r15 on my 1991 300d. They seem to stick out farther in the front and are rubbing on the inner fender well... Is there a chance I messed up something like the brake caliper? When I was driving with another 225lb guy in the car on one turn it sounded like something broke off. I thought the w126 wheels stuck out farther and the w124s were more inset. I measured the inside from hub to inner rim. The w124 was 1 inch deeper than the w126. Anyways, I'm putting the stock rims back on asap! Does anyone know if I could've messed something up by doing this?
