[R129 SL] AMG Wheels

Mon, 3 Feb 2003 19:27:16 -0500

Not for the Aero II.  The Aero II never came in an 8.5 and 9.5 offset
for the R129.  The R129 5-spoke 18x8.5 and 18x9.5 had the 25mm offset
for the 8.5" front wheel and 23mm offset for the 9.5" rear wheel.

Mike,

Your front and rear wheels may have different offsets so you need to
check both.

The size specifications are stamped/cast on every wheel.  It's usually
on the back of one of the spokes.  There is often other information as
well. Generally, the size specification is as follows: 8.5 x 18 ET35
(width x diameter and offset).  ET designates offset and is always
negative although this is not indicated.  While the wheel width and
diameter are in inches, the offset is in millimeters.  Very equal
opportunity.  Sometimes there is a letter after the width (e.g., 8.5J)
indicating the design of the lip on the wheel.

If you don't feel like pulling the wheels off the car, the lazy man's
approach to this problem is drive one side of the car up on a curb from
a driveway, then crawl underneath to look on the inside of the wheel
spokes with a flashlight.  You may need to roll the car forward a bit
more to rotate the spokes for visibility of the right spoke.  Also, be
very carful when backing the car back down so it doesn't slide off the
side of the curb and damaging the wheels/tires/body panels.

To be confident of the fit of those wheels on an SL, you'll want to see
the offsets be near 25mm.  The Aero II's in a staggered setup on the
SL500 would use 8.5" ET23 front and 9.5" ET25 rears with the same tire
sizes as the E55.

Satish,

Yes, they are the Aero II's (monoblocks) and I don't know the offset.
How can I determine the offset? I don't know if this will help, but when
I ordered them from the local MB dealer I ordered 4 - 18 X 8 AMG wheels
(and Michelin tires) because at the time my thought was to be able to
rotate the tires for longevity. What they received was the AMG
wheel/tire setup for the E55 or so they told me. They said this setup
would be more costly than what I had wanted but they offered them to me
for the same price and I accepted.

Thanks,

Mike
