Please refer to the diagram below.
LT
The “LT” indicates the tire is for light trucks or trailers.
ST
An “ST” is an indication the tire is for trailer use only.
“ST” tires are design for carrying heavy loads at
lower speeds. The Tire and Rim Association Standard
indicates that for operation at speeds up to 65 mph,
no change in maximum cold tire inflation pressure
or load is required. For speeds between 66-75 mph,
increase the maximum cold tire inflation pressure
10 psi.
Next number – 3 Digit
This three-digit number gives the width in millimeters
of the tire from sidewall edge to sidewall edge. In
general, the larger the number, the wider the tire.
Next number – 2 Digit
This two-digit number, known as the aspect ratio,
gives the tire’s ratio of height to width. Numbers of
70 or lower indicate a short sidewall for improved
steering response and better overall handling on dry
pavement.
R or D
The “R” stands for radial. The “D” stands for bias.
Next number
This two-digit number is the wheel or rim size.
U.S. DOT Tire Identification Number
This 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 it was
manufactured, and the last four numbers represent
the week and year the tire was built. For example,
the numbers 3197 means the 31st week of 1997.
The other numbers are marketing codes used at the
manufacturer’s discretion. This information is used to
contact consumers if a tire defect requires a recall.
Tire Ply Composition and Materials Used
The number of plies indicates the number of layers
of rubber-coated fabric in the tire. In general, the
greater the number of plies, the more weight a tire
can support. Tire manufacturers also must indicate
the materials in the tire, which include steel, nylon,
polyester, and others.
Max. Load Dual kg (lbs) at kPa (psi) Cold
This information indicates the maximum load and tire
pressure when the tire is used as a dual, that is, when
four tires are put on each rear axle (a total of six or
more tires on the vehicle).
Max. Load Single kg (lbs) at kPa (psi) Cold
This information indicates the maximum load and tire
pressure when the tire is used as a single.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure
that should ever be put in the tire under normal driv-
ing conditions.
Load Range
This information identifies the tire’s load carrying
capabilities and its inflation limits.
Tire Safety Tips
Preventing Tire Damage
• Slow down if you have to go over a pothole or
other object in the road.
• Do not run over curbs or other foreign objects in
the roadway, and try not to strike the curb when
parking.
Tire Safety Checklist
• Check tire pressure regularly (at least once a
month), including the spare.
• Inspect tires for uneven wear patterns on the
tread, cracks, foreign objects, or other signs of
wear or trauma.
• Remove bits of glass and foreign objects
wedged in the tread.
• Make sure your tire valves have valve caps.
• Check tire pressure before going on a long trip.
• Do not overload your vehicle. Check the tire
information placard or owner’s manual for the
maximum recommended load for the vehicle.
