Use of Low Aspect Ratio Tires
1. Standard tire
2. Low aspect ratio tire
Low aspect ratio tires for truck applications
(aspect ratio at 70%) have an air volume
20% to 30% smaller than that of standard
tires. When air begins to leak, therefore, low
aspect ratio tires adversely affect vehicle
operation much faster than standard tires.
Check air pressure of low aspect ratio tires
more often than standard tires using a tire
air pressure gauge.
Damaged Tires
Danger
It is dangerous to mount the wrong
size tire on a wheel. If you do so, the
tire/wheel can explode as air is being
added. This explosion may result in
severe personal injury or death. To
learn which wheels and tires are
correct, look at the "VIN, Weight
Rating, and Greenhouse Gas (GHG)
Emissions Plate" on the left side rear
pillar panel below the striker. Wheel
size is also stamped on the side of
each wheel.
To help avoid personal injury and
property damage if a wheel must be
changed, seek expert tire services.
Taking off and mounting tires on
wheels requires proper tools, safety
equipment and special training.
A person can be severely injured or
killed and damage can result from
using the wrong service methods.
Truck tires and wheels should be
serviced only by trained people using
the proper equipment.
Danger (Continued)
Do not put air back in a tire that has
been run flat, or is seriously low on
air, without first having the tire
taken off the wheel and the tire
checked for damage.
Never add air to your tires unless an
accurate pressure gauge is also used.
When putting air in a tire on the
vehicle, stand to the side and use a
clip-on check and hose extension. In
choosing the right tire pressure, be
careful not to exceed the maximum
pressure capability shown on the
tire; see the tire pressure charts in
this manual.
Tire mounting or repair can result in
serious personal injury or death,
if not performed correctly. This
section has detailed instructions for
proper wheel and tire replacement,
so be sure to read and follow them.
Truck fleet owners and operators:
You can get written instructions on
truck tire demounting, repair and
mounting from U.S. Tire
