Tire Identification Information
To maintain the load capacity of your motorhome, it is vitally
important to only replace worn or damaged tires with tires
with ratings equal to or higher than what was originally
equipped on your vehicle.
The illustration on the next page describes important tire infor-
mation that is embossed on every tire by the manufacturer.
P or LT: The “P” indicates the tire is for passenger
vehicles. “LT” indicates the tire is for light trucks.
NOMINAL WIDTH: This three-digit number
gives the width of the tire in millimeters from
sidewall edge to sidewall edge. The larger the
number, the wider the tire.
MAXIMUM LOAD RATING: This number
indicates the maximum load the tire can
carry.
MAXIMUM PERMISSIBLE:
INFLATION PRESSURE:
This number is
the greatest amount of air pressure that
should ever be put in the tire. This is NOT
the same as the vehicle manufacturer’s
recommended tire pressure.
TEMPERATURE:
The temperature rating
indicates how well the tire resists heat.
TRACTION: The traction rating indicates the
tire’s stopping ability on wet pavement.
ASPECT RATIO: This two-digit number gives the
tire’s ratio of height and width.
TREADWEAR:
The treadwear rating
indicates how long the tire should last.
The higher the number, the longer it will
take for the tires to wear down.
RIM DIAMETER CODE: This two-digit number
is the wheel or rim diameter in inches.
LOAD INDEX:
This two-digit or three-
digit number indicates how much
weight each tire can support.
SPEED RATING: The speed rating indicates
the maximum speed capability of the tire.
This rating includes speeds from 99 MPH to
above 186 MPH.
U.S. DOT TIRE IDENTIFICATION NUMBER: This
number begins with the letters “DOT” and indicates
that the tire meets all Federal standards. The next two
or three numbers or letters are the manufacturer’s
plant location. The last four numbers represent the
week and year the tire was made.
M+S:
This indicates the tire has some mud and
snow capability.
R:
The “R” stands for radial. Radial tires have been
the industry standard for more than 20 years.
