When they appear even with the outside of the tread, it is
time to replace your tires. Another method for checking
tread depth is to place a penny in the tread with Lincoln’s
head upside down and facing you. If you can see the top of
Lincoln’s head, you are ready for new tires.
Tire Balance and Wheel Alignment
To avoid vibration or shaking of the vehicle when a
tire rotates, the tire must be properly balanced. This
balance is achieved by positioning weights on the wheel to
counterbalance heavy spots on the wheel and tire assembly.
A wheel alignment adjusts the angles of the wheels so that
they are positioned correctly relative to the vehicle’s frame.
This adjustment maximizes the life of your tires and prevents
your trailer from veering to the right or left when driving
on a straight, level road. These adjustments require special
equipment and should be performed by a qualified technician.
Tire Repair
The proper repair of a punctured tire requires a plug for the
hole and a patch for the area inside the 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.
Tire Rotation
Rotating tires from front to back and from side to side can
reduce irregular wear (for vehicles that have tires that are all
the same size). The generally recommended rotation period is
every 5,000 miles.
Uniform Tire Quality Grading System (UTQGS)
To help consumers compare tread wear rate, traction
performance and temperature resistance, the federal
government requires tire manufacturers to grade tires in these
three areas. This grading system, known as the Uniform Tire
Quality Grading System, provides guidelines for making relative
comparisons when purchasing new tires. You also can use this
information to inquire about the quality of tires placed on new
vehicles.
Although this rating system is very helpful when buying
new tires, it is not a safety rating or guarantee of how well a
tire will perform or low long it will last. Other factors such as
personal driving style, type of car, quality of the roads, and tire
maintenance habits have a significant influence on your tire’s
performance and longevity.
Tread wear grades are an indication of a tire’s relative
wear rate. The higher the tread wear number is, the longer it
should take for the tread to wear down. For example, a tire
grade of 400 should wear twice as long as a tire grade of 200.
Traction grades are an indication of a tire’s ability to stop
on wet pavement. A higher graded tire should allow you to
stop on wet roads in a shorter distance than a tire with a lower
grade. Traction is graded from the highest to lowest as AA, A,
B, or C.
Temperature grades are an indication of a tire’s resistance
to heat. Sustained high temperature (for example, driving
long distances in hot weather), can cause a tire to deteriorate,
leading to blowouts and tread separation. From highest to
lowest, a tire’s resistance to heat is graded as A, B, or C.
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.
Information on Trailer Tires
Please refer to the photo below.
ST: The ST indicates that the tire is for trailer use.
Next number: 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: 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 payment.
R: The R stands for radial. Radial ply construction of tires
has been the industry standard for the past 20 years.
Next 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.
Tire Safety Tips
Preventing Tire Damage
• Slow down when crossing 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.
