Tires and wheels
General:
Tire width
Tire code
Depending on the design standards used,
the tire size molded into the sidewall may
have no letter or a letter preceding the tire
size designation.
The tire width 1 (୴ page 314) indicates
the nominal tire width in mm.
The tire code 3 (୴ page 314) indicates
the tire construction type. The “R” stands
for radial tire type. Letter “D” means diag-
onal or bias ply construction; letter “B”
means belted-bias ply construction.
Aspect ratio
No letter preceding the size designation
(as illustrated above): Passenger car tire
based on European design standards.
The aspect ratio 2 (୴ page 314) is the
dimensional relationship between tire
section height and section width and is
expressed in percentage. The aspect ratio
is arrived at by dividing section height by
section width.
At the tire manufacturer’s option, any tire
with a speed capability above 149 mph
(240 km/h) can include a “ZR” in the size
designation (for example: 245/40 ZR 18).
For additional information, see “Tire speed
rating” (୴ page 316).
Letter “P” preceding the size designation:
Passenger car tire based on U.S. design
standards.
Letter “LT” preceding the size designation:
Light Truck tire based on U.S. design
standards.
Rim diameter
The rim diameter 4 (୴ page 314) is the
diameter of the bead seat, not the
diameter of the rim edge. Rim diameter is
indicated in inches (in).
Letter “T” preceding the size designation:
Temporary spare tires which are high
pressure compact spares designed for
temporary emergency use only.

Automotive readers have rated 2008 Mercedes-Benz CLS550 CLS63 AMG W219 Owners Manual 5.0 out of 5.0 based on 2 product reviews. This is exactly what I've been looking for and need. Great info in perfect detail and limited pics help as well.
Great having the manual saved on my tablet versus having to get the hard copy from within the vehicle. It's very thorough and complete, much appreciated
