Tire Sizes for Sprinter Vehicles
1. Vehicles with programmed top speed limit of 68
mph (109 km/h) only.
Design Standard
Depending on the design standards used, the tire size
molded into the sidewall may have no letter or a letter
(1) preceding the tire width or the tire load rating
designation.
Letter "LT" preceding the tire width designation:
Light Truck tire based on U.S. design standards.
Letter "C" preceding the tire load rating designation:
Commercial vehicle tire based on European design
standards.Tire Width
The tire width (2) indicates the nominal tire width in
mm.
Aspect Ratio
The aspect ratio (3) 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.
Tire Code
The tire code (4) indicates the tire construction type.
The “R” stands for radial tire type. Letter “D” means
diagonal or bias ply construction; letter “B” means
belted-bias ply construction.
Rim Diameter
The rim diameter (5) is the diameter of the bead seat,
not the diameter of the rim edge. Rim diameter is
indicated in inches (in).
Tire Load Rating
The tire load rating (6) is a numerical code associated
with the maximum load a tire can support. Sprinter type

194 STARTING AND OPERATING
For example, a load rating of 115 corresponds to a
maximum load of 2680 lbs (1215 kg) the tire is designed
to support.
If two values are given (as illustrated), the first value,
preceding the slash "/", applies to single tires (rear
axle).
The second value, succeeding the slash "/", applies to
twin tires (dual wheel rear axle).
The commercial vehicle tires based on European
standards may have an additional value in the
parentheses (as illustrated). In such case, the value
preceding the parentheses is valid for European
countries and the parenthesized for the USA and
Canada.
Refer also to "Maximum Tire Load" where the
maximum load associated with the load index is
indicated in kilograms and lbs.
NOTE: Tire load rating (6) and tire speed rating (7) are
also referred to as "service description".
WARNING!
The tire load rating must always be at least half of
the GAWR of your vehicle. Otherwise, tire failure
may be the result which may cause an accident
and/or serious personal injury to you or others.
For information on GAWR, refer to "Tire and
Loading Terminology".
Always replace rims and tires with the same
designation, manufacturer and type as shown on
the original part.
WARNING!
Do not overload the tires by exceeding the specified
load limit as indicated on the Tire and Loading Infor-
mation placard on the driver’s door B-pillar.
Overloading the tires can overheat them, possibly
causing a blowout.
Overloading the tires can also result in handling
or steering problems, or brake failure.

Tire Speed Rating
The tire speed rating (7) indicates the approved
maximum speed for the tire.
The commercial vehicle tires based on European
standards may have an additional index in the
parentheses (as illustrated). In such case, the index
preceding the parentheses is valid for European
countries and the parenthesized for the USA and
Canada.
NOTE: Always observe the speed rating of the winter
tires installed on your Sprinter vehicle. If the
maximum speed for which your tires are rated is belowthe speed rating of your Sprinter vehicle, youmust
place a notice to this effect where it will be seen by the
driver.
Such notices are available at your tire dealer or any
authorized Sprinter Dealer.
NOTE: Tire load rating (6) and tire speed rating (7) are
also referred to as "service description".
WARNING!
Even when permitted by law, never operate a vehicle at
speeds greater than the maximum speed rating
of the
tires.
Exceeding the maximum speed for which tires are
rated can lead to sudden tire failure, causing loss
of vehicle control and possibly resulting in an
accident and/or personal injury and possible
death, for you and for others.
Index Speed Rating
F up to 50 mph (80 km/h)
G up to 56 mph (90 km/h)
J up to 62 mph (100 km/h)
K up to 68 mph (110 km/h)
L up to 74 mph (120 km/h)
M up to 80 mph (130 km/h)
N up to 87 mph (140 km/h)
P up to 93 mph (150 km/h)
Q up to 100 mph (160 km/h)

DOT, Tire Identification Number (TIN)
(1) DOT
(2) Manufacturer’s identification mark
(3) Tiresize
(4) Tire type code (at the option of the tire
manufacturer)
(5) Date of manufacture NOTE: Data shown on tire are for illustration purposes
only. Actual data on tires are specific to each vehicle
and may vary from data shown in the illustration.
U.S. tire regulations require each new
tiremanufacturer or tire retreader to mold a TIN into or
onto a sidewall of each tire produced.
The TIN is a unique identifier which facilitates efforts by
tire manufactures to notify purchasers in recall situations
or other safety matters concerning tires and gives
purchasers the means to easily identify such tires.
The TIN is comprised of "Manufacturer’s identification
mark", "Tire size", "Tire type code" and "Date of
manufacture".
The TIN may be found on one or both sides of the tire
however the date code may only be on one side. Tires
with white sidewalls will have the full TIN including
date code located on the white sidewall side of the tire.
Look for the TIN on the outboard side of black sidewall
tires as mounted on the vehicle.
If the TIN is not found on the outboard side then you
will find it on the inboard side of the tire. In this case,
the tire must be remounted. Make sure the TIN is

Tire Size
The code (3) indicates the tire size.Tire Type Code
The code (4) may, at the option of the manufacturer, be
used as a descriptive code for identifying significant
characteristics of the tire.
Date of Manufacture
The date of manufacture (5) identifies the week and
year of manufacture.
The first two figures identify the week, starting with
“01” to represent the first full week of the calendar
year. The second two figures represent the year.
For example, "0301" represents the 3rd week of 2001.
NOTE: Prior to July 2000, tire manufacturers were only
required to have 1 number to represent the year in
which the tire was manufactured.
For example, "031" could represent the 3rd week of
1981 or 1991.
NOTE: If the date of manufacture code indicated on the
tire is less than 4 figures, do not use it.

Rotation pattern for single and dual rear wheels
Single Rear Wheels:
Rotate the tires by axle. Never change the direction
of rotation of your tires. Make sure that on one axle
just one type of tire (same size, type construction,
load and speed rating) is used.
Dual Rear Wheels:
Rotate front tires by axle and the outer rear tire side
to side if there is no approved direction of rotation.
The tires used on dual wheel assemblies should be
WARNING!
In order to avoid loosing a wheel and in order to re-
duce the risk of fatal or serious injuries or vehicle
damage, please follow these safety instructions:
Always replace wheel bolts that are damaged or
rusted.
Never apply oil or grease to wheel bolts.
If a wheel hub thread is damaged, you must not
drive the vehicle. Consult a qualified specialist
workshop.
Only use genuine wheel bolts approved from the
vehicle manufacturer and specified for your
vehicle’s rims. Check tightness of wheel bolts or
nuts regularly and retighten with a torque wrench,
if necessary. Tighten wheel bolts or nuts in a cross-
pattern sequence. After changing a wheel, the
wheel bolts or nuts must be tightened once the
vehicle has been driven for about 30 miles (50 km).
If new or repainted wheels are fitted, the wheel
bolts or nuts must be retightened again after about
600 to 3000 miles (about 1000 to 5000 km).
