Land Rover Defender: Tire markings
Make sure the relevant safety warnings
have been read and understood before
replacing a tire.
All replacement tires must be the same
specification as the original equipment
tires, except for approved winter tires,
off-road tires, and Professional Off-Road
(POR) tires. If in doubt, consult a
retailer/authorized repairer. Failing to
comply with these rules can lead to
accidents, potentially causing serious
injury or death.
- P indicates that the tire is for
passenger vehicle use. The index is
not always shown.
- The width of the tire from sidewall
edge to sidewall edge, given in mm.
- The aspect ratio, also known as the
profile, gives the sidewall height as a
percentage of the tread width. For
example, if the tread width is 205 mm
and the aspect ratio is 50, the sidewall
height will be 102 mm.
- R indicates that the tire is of radial ply
construction.
- The diameter of the wheel rim, given
in inches.
- The load index for the tire. The load
index specifies the maximum load the
tire can carry at the speed indicated
by the tire's speed rating. The index
is not always shown.
- The speed rating denotes the
maximum speed at which the tire
should be used for extended periods.
- U.S. DOT Tire Identification Number
(TIN): The TIN begins with the letters
DOT and indicates that the tire meets
all federal standards. The next two
numbers or letters are the plant code
where the tire was manufactured. The
last four numbers are the date of
manufacture. For example, if the
number is 3109, the tire was made in
the 31st week of 2009. The other
numbers are marketing codes used at
the manufacturer's discretion. The
information can be used to contact
consumers if a tire defect requires a
recall.
- M+S or M/S indicates that the tire has
been designed with some capability
for mud and snow.
- The winter tires symbol identifies
dedicated winter tires.
- The number of plies in both the tread
area and the sidewall area. The
number of plies indicates how many
layers of rubber-coated material make
up the structure of the tire. Information
is also provided on the type of
materials used.
- Wear rate indicator: A tire rated at 400,
e.g., lasts longer than a tire rated at
200.
- The traction rating grades a tire's
performance when stopping on a wet
road surface. The higher the grade,
the better the braking performance.
The grades, from highest to lowest,
are: AA, A, B, and C.
- The maximum load which can be
carried by the tire.
- Heat resistance grading: The tire's
resistance to heat is grade A, B, or C,
with A indicating the greatest
resistance to heat. The grading is
provided for a correctly inflated tire
which is being used within its speed
and loading limits.
- The maximum inflation pressure for
the tire. The maximum inflation
pressure should not be used for
normal driving.
Note: Approved tires are generally
identified by the brand mark J, LR, or J
LR. Brand markings are specifically
excluded for winter and POR tires.
