Preventing Tire Damage:
• Slow down if you have to go over a pothole or other object in the road.
• Do not run over foreign objects in the roadway, and try not to strike the curb when parking.

• 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 any other 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 for the maximum recommended load for the
vehicle.
• If you are towing a trailer, remember that some of the weight of the loaded trailer is transferred to the towing
vehicle.

Federal law requires tire manufacturers to place standardized information on the sidewall of all tires. This infor-
mation identifies and describes the fundamental characteristics of the tire and also provides a tire identification
number for safety standard certification and in case of a recall.
P
Indicates the tire is for passenger vehicles.
n
ext
(3 d
igit
) n
umber
Gives the width in millimeters of the tire from sidewall edge
to sidewall edge. In general, the larger the number, the wider
the tire.
n
ext
(2 d
igit
) n
umber
Gives the tire’s ratio of height to width, (known as the aspect
ratio). Numbers of 70 or lower indicate a short sidewall for
improved steering response and better overall handling on
dry pavement.
r
‘R’ stands for radial. Radial ply construction of tires has been
the industry standard for the past 20 years.
n
ext
number
This two-digit number is the wheel or rim diameter in inches.
If you change your wheel size, you will have to purchase new tires to match the new wheel diameter.
n
ext
number
This two or three digit number is the tire’s load index. It is a measurement of how much weight each tire can sup-
port. If you are unsure, contact a local tire dealer. Note: You may not find this information on all tires since it is not
required by law.
m+S
‘M+S’ or ‘M/S’ indicates that the tire has some mud and snow capability. Most radial tires have these markings;
hence, they have some mud and snow capability.
