tire that surrounds the puncture hole. Punctures through the tread can be repaired if they are not
too large, but punctures to the sidewall should not be repaired. Tires must be removed from the rim
to be properly inspected before being plugged and patched.
1.5.9 Tire Fundamentals
Federal law requires tire manufacturers to place standardized information on the sidewall of all tires.
This information 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.
1.5.9.1 Information on Passenger Vehicle Tires
Please refer to the diagram below:
P - The “P” indicates the tire is for passenger vehicles.
First 3 numbers - 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 2 numbers -
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 -
The “R” stands for radial. Radial ply construction of tires has been the industry standard for
the past 20 years.
Next 2 numbers - 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.
Next 2 or 3 numbers - This two or three-digit number is the tire’s load index. It is a measurement
of how much weight each tire can support. You may find this information in your owner’s
manual. If not, contact a local tire dealer. Note: You may not find this information on all tires
because it is not required by law.
M+S - The “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.
